There are 2 things I’ve heard over the years, that I would like clearing up. Both of which I’ve thought, ‘“nah not sure about that” but haven’t been able to verify one way or the other.

1. 2 vehicles travelling at 60 mph crashing head-on is the equivalent, for each vehicle, of hitting a stationary immovable object at 120 mph.

2. Nigel Mansell once said something like, through a series of corners going from a left hand bend at 4g to a right hand bend at 4g is 8g in total.

Can anyone prove these statements right or wrong?

Very interesting,

The first quote was from an uncle of mine who was a police officer and he was referring to crashes he had seen, but the Myth Busters clip is quite clear.

And the second one also seems to be untrue.

But can an F1 car turn instantaneously? Maybe there would be a transition between the opposite G forces? I don’t know.

Cheers
