Indeed, how hard to you think you have to hit your head on concrete before sustaining a serious injury?  Now imagine if your head hit the pavement without the helmet on.

.

.
I was surprised to find out what constitutes a head injury.
Also how much blood there is: after just a small gash on the scalp, there's blood all OVER the place.
.
EMTs have to abide by lots of rules, and there are more than the usual number of rules for head injuries than for other categories.
Broken limb bones, open laceration wounds, vomiting, abrasions, bullet wounds, all those things have procedures attached.
But when it comes to head injury, suddenly you get another level of complications.
.
So what is a "head injury?"
It's not only any visible blood on the head, wound, or visible bruise or abrasion on the head (from the neck up).
It's also any set of symptoms that indicate that MAYBE there has been a head injury, even if no visible clues on the head.
.
Whenever an EMT has suspected head injury there is a series of checks he has to perform.
Stuff like check temperature, eye pupil dilation including right vs. left, consciousness/responsiveness to sound (if possible, low noise environment), ability to answer questions or follow by eye motion a moving object, throat obstruction, breathing pattern, ability to sit up, and so on.
.
A sharp blow to the head can result in otherwise not immediately obvious but very consequential conditions such as brain swelling, or internal bleeding, or fluid buildup, sudden unconsciousness, loss of speech, vision, hearing, broken neck, etc.
.
The Hollywood version of someone getting knocked out, and then after a minute or two regaining consciousness and everything's fine, is pretty much urban legend. It's only RARELY that simple.
.
Doctors and nurses have to keep watch on a head injury patient sometimes for DAYS to be sure everything is okay.
And once it's been established that a complete recovery has happened, they still ask even weeks or months later if there have been any recurring symptoms.
.
So while it might be thought of as "tough" or "manly" to ignore safety precautions to protect one's head, you ought to become informed about the sometimes fatal consequences but more often life-changing effects of head injury.
.
You might look "cool" or carefree zipping around without a helmet on, and you might get away with it your whole life.
.
Or, you might end up in a coma the rest of your life the first time you slip and fall off a bicycle -- and everything in between.
.
The wise course of action demands that one would at least become cognizant of the dangers involved.

Ah, but the trouble is if you're going down a slope you can pick up quite a large pace on those, I don't use scooters so I'm not sure exactly how they're designed but breaking [braking] on them is probably still risky business. And with your hands being on the handlebars, there's a good chance if you suddenly get thrown off that you won't be able to put them in front of your head before it smacks off the ground.


I think the helmets are fine, it's adults riding scooters designed for kids that's wussy.

.

.
The braking function for a scooter is limited to lifting the handlebar upwards and the front wheel off the ground so as to engage the drag bar behind the rear wheel, which scrapes the ground, and the friction is supposed to slow you down; but it's not all that effective, and using it requires practice since it's a bit destabilizing and you could end up falling over if you don't keep your balance well.
.
It's true that falling off a scooter and letting go of the handlebars in time to use your arms to protect your head is something that won't be happening automatically, since nobody is going to bother practicing it in advance.
.
I didn't use a scooter when I was a child, as they became popular for children in later years.
I now know adults who like to use them because they have fond memories of using them as a child.
When you've kept up your skills over the years doing something you enjoy, why give it up if it's fun?
It's rather a shame when people are overly concerned with what someone else might think about how they look to others.
Obsession with the image you project can become way too important.
I know an avowed Communist who wouldn't DREAM of doing anything that might make him look "wussy."
But knowing all the heresies he proudly and tenaciously adheres to, I have no question that he's headed straight to hell.
And there is absolutely nothing I can do about it, beyond pray for his conversion.
Is what other people thought of them what mattered most to the saints?
When you face your final judgment is Our Lord going to ask you why you were not sufficiently preoccupied with your public image?
Is your popularity or public approval in any way related to your holiness or your state of grace?
.
It seems to me that we ought to be concerned first with what GOD thinks, not what man thinks of us.
In fact, obsession with what man thinks of you is what we call "worldliness." 
In previous centuries, before Catholics forgot what it means to be Catholic, it was a very commonly understood great compliment to have someone say about you, that you were in the world but not of the world.

The lyft helmet thingy..................
.


.
Buried in the list of questions is a curious factoid:  Lyft scooters are battery powered, with a motor drive, right grip throttle (like motorcycles), and can accelerate to get you going places faster than leg power can. The couple kicking the ground in the OP were getting their scooters STARTED -- once the battery and motor engage this way, you can stand still on the platform, twist the right handle, and the scooter does all the pushing for you. So what I had thought was a BRAKE in the front wheel rim is actually a MOTOR, so they most likely use a REVERSE GENERATOR BRAKING FUNCTION that stores the kinetic energy of your motion forward back into the battery when you apply the brakes, rather than wasting the energy as heat from friction of brake pads slowing you down. But they don't bother to explain that on the website, apparently.

.
Okay, now for the real fun.
.
You can be fined $25 for keeping your Lyft e-Vehicle Product (LeVP, a.k.a. scooter) longer than the maximum rental period: 12 hours.
You have to be 18 to rent an LeVP in Colorado, and you can't let ANYONE ELSE use it, lest you be fined!!
If you use, leave or deactivate your LeVP outside the Designated Area and Lyft has to go fetch it, it's a $100 fee.
At their sole discretion, you can be charged $600 for engaging in any of several violations of policy.
Violations include but are not limited to your performance of the required SAFETY CHECK done before each use of the LeVP.
Another example of a violation could be your failure to use an approved helmet (your use of an unapproved helmet).
You must obey all laws relating to the use, parking and operation of LeVPs.
You are responsible to learn what a docking station is, and what an unrechargeable area is, among other things.
Where you can operate them, how to get on or off them, what you can do when on or off them -- lots of RULES.
This is looking more like an entirely new world of quasi-reality built up around LeVPs.

Such releases are intended to be general and complete releases of all Claims. The Released Persons may plead such releases as a complete and sufficient defense to any Claim, as intended third party beneficiaries of such releases.
Releasing Party hereby acknowledges that he/she has been advised by legal counsel, is familiar with and fully understands the provisions of California Civil Code Section 1542 which provides as follows: “A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.” Having been so advised, Releasing Party nevertheless elects to and does assume all risks for Claims known or unknown, suspected or unsuspected, heretofore arising from the subject of this Section 3, and specifically waives any rights it may have under Section 1542, as well as under any other statute or common-law principle in any jurisdiction with a similar effect.
3.2 Disclaimers. YOU DO HEREBY ACKNOWLEDGE AND AGREE THAT YOUR USE OF ANY OF THE SERVICES, PRODUCTS, OR RELATED EQUIPMENT IS AT YOUR SOLE RISK. TO THE FULLEST EXTENT PERMITTED BY LAW, AND WITH RESPECT TO YOUR USE OF ANY OF THE SERVICES, PRODUCTS, OR RELATED EQUIPMENT, LYFT AND ALL OTHER RELEASED PERSONS DISCLAIM ALL EXPRESS AND IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. ALL OF THE SERVICES, PRODUCTS, AND RELATED EQUIPMENT ARE PROVIDED “AS IS” AND “AS AVAILABLE” (AND YOU RELY ON THEM SOLELY AT YOUR OWN RISK). LYFT AND ALL OTHER RELEASED PERSONS DO NOT REPRESENT OR WARRANT THAT ANY OF THE SERVICES, PRODUCTS, OR RELATED EQUIPMENT WILL BE IN GOOD REPAIR OR ERROR-FREE, AND DELAYS, OMISSIONS, INTERRUPTIONS, OR INACCURACIES COULD EXIST WITH RESPECT TO ANY OF THE SERVICES, PRODUCTS, OR RELATED EQUIPMENT.

THE TOTAL LIABILITY OF LYFT AND ALL OTHER RELEASED PERSONS FOR ALL CLAIMS, INCLUDING THOSE BASED IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STATUTE, OR OTHER GROUNDS, IS LIMITED TO THE SUM OF $100. SOME JURISDICTIONS DO NOT ALLOW FOR LIMITED LIABILITY OR EXCLUSION OF IMPLIED WARRANTIES; AND, IF ANY OF THOSE LAWS APPLY TO YOU, THEN SOME OR ALL OF THE ABOVE DISCLAIMERS, EXCLUSIONS, OR LIMITATIONS MIGHT NOT APPLY TO YOU, AND YOU MIGHT HAVE ADDITIONAL RIGHTS.
3.4 Assumption of Risk by You. You are solely and fully responsible for the safe operation of the Product at all times. You agree that Products are machines that may malfunction, even if the Product is properly maintained, and that such malfunction may cause injury. You agree that riding a Product and the Services involve many obvious and not-so-obvious risks, dangers, and hazards, which may result in injury or death to you or others, as well as damage to property, and that such risks, dangers, and hazards cannot always be predicted or avoided. You agree that such risks, dangers, and hazards are your sole responsibility, including, but not limited to, choosing whether to wear a helmet as required by law or utilize other protective gear. You agree that if your use of any of the Products or Services causes any injury or damage to another person or property, then you may be liable for all resulting injuries, damages, and related costs. By choosing to operate a Product, you assumes full and complete responsibility for all related risks, dangers, and hazards, and you agree that Lyft and all other Released Persons are not responsible for any injury, damage, or cost caused by you with respect to any person or property, including the Product itself.
3.5 Indemnification. You will indemnify and hold the Released Persons harmless from all losses, suits, claims or other proceedings arising out of or relating to your use of Products and any breach of the terms of this Addendum; provided, however, that Released Persons must notify you as soon as practicable after the date notice of such loss, suit, claim or other proceeding is served on Released Persons directly (as opposed to service on a statutory agent for service of process) or otherwise brought to the attention of Released Persons.
Additional Terms of Use.
4.1 Safety Check. Before each use of a Product, you shall conduct a basic safety inspection of the Product, which includes inspecting the following: (i) trueness of the wheels; (ii) safe operation of all brakes and lights; (iv) good condition of the frame; (v) sufficient battery charge power; and (vi) any sign of damage, unusual or excessive wear, or other mechanical problem or maintenance need. You agree not to operate the Product if there are any noticeable issues, and to immediately notify customer service to alert Lyft of any problems.
4.2 Lost or Stolen Product. A Product may be deemed lost or stolen if (a) the Product is not returned within 12 consecutive hours, (b) the Product’s GPS unit is disabled, (c) the Product is parked on private property, in a locked area, or in any other non-public space for more than ten minutes after a ride ends, (d) the Product moves more than thirty feet after a rental has ended and Lyft believes such movement was not caused by another rider or authorized third party, or (e) other facts and circuмstances exist that suggest to Lyft in its reasonable, good faith determination that a Product has been lost or stolen. You and Lyft agree that the last rider of a Product shall be responsible for a lost or stolen Product unless facts and circuмstances suggest otherwise to Lyft in its reasonable, good faith determination. If Lyft deems a Product lost or stolen, Lyft shall have the authority to take any and all actions it deems appropriate (with respect to the last rider of a Product or otherwise), including (without limitation) obtaining restitution and other appropriate compensation and damages and filing a police report with local authorities. The data generated by the Lyft’s systems is conclusive evidence of the period of use of a Product by a rider, including you. You must report Product disappearance or theft to Lyft immediately or as soon as possible.
4.3 Helmets; Safety. Lyft recommends that you wear a Snell, CPSC, ANSI or ASTM approved helmet that has been properly sized, fitted and fastened according to the manufacturer’s instructions. You agree that none of Lyft and its Released Parties are liable for any injury suffered by tiy while using the Service, whether or not you are wearing a helmet at the time of injury. You may need to take additional safety measures or precautions not specifically addressed in this Addendum.
4.4 Vehicle Routes. You agree that Lyft does not provide or maintain places to ride Products, and that Lyft does not guarantee that there will always be a safe place to ride a Product. Roads, bicycle lanes, and other accessible areas may become dangerous due to weather, traffic, or other hazards.
4.5 Limitations on Product Rental. You agree that Lyft is not a common carrier. Alternative means of public and private transportation are available to the general public and to you individually, including public buses and rail service, taxis, and pedestrian paths. Lyft provides Products only as a convenience, and such rental availability is intended to be used only by those persons who are able and qualified to operate a Product on their own and who have agreed to all terms and conditions of this Addendum.
4.6 Limitations on Availability of Service. Lyft makes every effort to provide the Service 365 days per year, but does not guarantee that the Service will be available at all times, as force majeure events or other circuмstances might prevent Lyft from providing the Service. Access to the Service is also conditioned on the availability of Products. Lyft does not represent or warrant the availability of any Service or the availability of any Product at any time. You agree that Lyft may require you to return a Product at any time.
Lyft Product Rental Privacy Policy Addendum
This Lyft Product Rental Addendum (“Privacy Addendum”) is an addendum to the Privacy Policy (www.lyft.com/privacy) between you and Lyft, and it sets forth additional terms and conditions that are applicable in the market in which you use Products on the Lyft Platform, including but not limited to use of our application, website, and other Products and Services. Capitalized terms not otherwise defined herein have the meaning set forth in the Privacy Policy and Addendum.
1. Information We Collect
A. Information You Provide to Us
When you initiate an e-Vehicle ride, you may share with Lyft docuмentation of your age by, for example, uploading a photo of your driver’s license. You may also share photos of the Product and its location with us to help us understand the status of the scooter and whether it has been used in compliance with our Agreement and Addendum.
If you communicate with us directly, we may receive additional information about you. For example, when you respond to any survey about the Lyft Platform or provide feedback about your experience, we will receive your name, email address, phone number, the contents of the communication and attachments you may send to us, and other information you choose to provide.
B. Information We Collect When You Use the Services and Products
Lyft Products may collect precise location at all times, and may transmit your location to Lyft during your use of the Product. We may also collect the precise location of your device when the app is running in the foreground or background, including for a period of five minutes after a ride in order to determine whether you have left the Product and ended your ride.
Your location information is necessary for things like determining ride start and stop locations, calculating charges for rides, and ensuring Products are used in compliance with our Agreement and Addendum (e.g., within certain service areas).

These things are foot powered! They don't go that fast. Even if they fell over, they're not going to crack their skull open. People are such wusses these days!

You're no higher off the ground than when you're walking on foot. Why not wear a helmet while walking as well -- "for safety" of course? You never know when you're going to fall, trip, or get pushed down.

Heaven help us if we're ever invaded.

They look like a couple of retarded dorks. I'm sure they're very nice people, but they look like complete retards.

.
1.  These things are NOT foot-powered, but battery-powered, motor-driven, with a top speed 15 mph, like a horse. 
.
2.  Falling off a powered scooter at 15 mph and hitting your head against a concrete wall could most definitely crack your skull open.
.
3.  You're exactly 4" higher off the ground riding this motorized scooter, than you are when walking on foot. 
       4" translates to about a 10% increase in the likelihood of incurring serious injury when falling down.
.
4.  If we're invaded, Lyft e-Vehicle Products will no doubt suddenly become unavailable for rent.
.
5.  The retarded dorks in the photo are enthusiastically and actively engaged in a whole new world of virtual reality. 
.
6.  Whether this new virtual reality is one exclusively for complete retards is a question yet to be resolved. 
     Certainly, Lyft isn't spending $million$ setting up a national and potentially international network, just for complete retards. 

.
Same couple as in OP 
Looks like Lyft is trying to foster a positive image for wearing helmets
The only online images I can find of scooter users wearing helmets are these Lyft images.

.
The man is wearing a backpack, which is not prominent in the OP photo.
These are both photos attached to Lyft e-Vehicle Products being used in their Denver pilot program.

I couldn't find a parts list, but similar electric bicycle batteries cost $300 to replace.
