Seems that heliocentrists love to hide behind non-speed measurements, such as the earth rotates at "x degrees" or "rpm's". This is just a clever way to hide the illogical idea of an earth spinning at over 1,000 mph.
Your car is going the same direction/speed as the coffee. This is not an apples-apples comparison of an earth rotating one direction (at over 1,000 mph) and a train going the opposite direction (at 60 mph). It makes no sense that this could work.
While I'm currently holding heliocentrism and geocentrism to be equal from a scientific point of view (just two different conventions regarding two different coordinate systems), the idea of a moving and spinning Earth is not illogical. As you only feel a
change in velocity, it's entirely plausible to not feel a thing while standing on a rotating ball that's whizzing through space, as long as the ball doesn't suddenly change it's direction, speed or rate of rotation.
Or going back to the analogy, the coffee cup has it way worse in the quickly accelerating and decelerating car than humans on a gigantic Earth ball that moves at pretty constant rates (there are slight, subtle changes over the year though).
The train going WITH the rotation of the earth (1,000 + 60 mph = 1,060) would have totally different physics than the train going AGAINST the rotation (-60mph vs 1000 mph = 940 mph). The train going against the rotation wouldn't be able to move and would be pushed backwards at a very high speed.
You don't seem to have grasped the concept of relativity. If I'm standing on a ball that's moving with 1,000 mph and start to walk in the same movement direction with say, 5 mph, I now have an absolute speed of 1,005 mph as viewed from an absolute frame of reference. However from my frame of reference, I only changed my speed by 5 mph, which is quite different. If I now stop and turn around, then happen to start walking against the direction of the ball with the same speed of 5 mph, I'll still only feel the change of speed and I won't feel that my absolute speed is now only 995 mph.
