POINT, COUNTERPOINT
Via e-mail --
Point: Regarding the Ford Focus 120 mph crash test video on your Facebook page, I'd like to clarify one thing. A 120 mph impact into a stationary object is equivalent to a head-on collision of two vehicles both going 60 mph ... and that could happen any day.

Counterpoint: No it isn't, fortunately. According to Newton's third law, the collision's force would be 1x per car (2x) but would also be divided per car (back to 1x). So a car going 60 mph crashing into another car going 60 would have the same effect as crashing into a wall at 60.
