This question is about perception of speed.


If you are sitting still, not moving in any direction, and are passed by a car going 100 mph; will it look the same as if you are traveling in a car going 100 mph, and get passed by a car going 200 mph? So will there be any difference in the distance put between you over a fixed amount of time, between the two scenarios?

In both scenarios, the passing car is traveling 100 mph faster than the perspective point (you). There is only one difference as far as I can tell. When you are sitting still, for every 1ft the passing car travels away from you, you don't move. When you are driving 100mph, and are passed by the car moving 200 mph, for every 2 ft the passing car travels, you make up 1 of those feet.


I haven't put much thought into this one, but I suspect that it can be solved in 2 minutes with a simple distance traveled over time equation. I am no good at math, so I can't come up with said equation.

Have fun.
