Scenario:
Two vehicles pass each other on a highway moving at 100km's an hour; from a stationary position beside the road you witness these cars pass each-other directly in front of you: from your perspective these cars are moving at 100km's an hour.
My Question: If you were inside either one of the 2 cars, looking straight out the window to where the other car would cross, would you perceive the vehicle to be moving at 200km's an hour as it passed you- due to both cars moving at 100km's in opposite directions?
I'm unsure if thats right or not- whenever I personally travel by car and bare-witness to another vehicle pass my window in the opposite direction at the same speed, it seems to always be moving much faster than it really is, assuming it was only because of the speed I was going when passing it.
Is this correct?
