Question:
When you are driving side by side with another car, why does the other car appear to be not moving, even though it is moving with the same speed as your car?


Replies:
It appears to be standing still because with respect to your frame of reference (your car) it is not moving. This assumes that your car and the other one are not moving at, or near, the speed of light.
