1. The problem statement, all variables and given/known data
If i was driving a car with no speed and there was another car i would see beside it moving with a speed forward, wouldnt it seem like i was going backwards?

2. Relevant equations

3. The attempt at a solution

the car with a speed is driving at x speed and mine is driving at 0 speed, right? So if x speed in the time "T" drives the car forward it seems as if i look outside my car that the other car is stationary but my car is moving.

if you don't look at the tires, yes it would. And this is called the relative speed, everything depends on your frame of referance. if u want to make urself stable, the other car would be moving. If u want to make urself moving and everything else not moving, this will be the case

exactly the car seems to be driving backwards if we assume the surroundings are just air :zzz:
