Are you sure? A 200kg motorbike hitting a car at 160mph is going to exert the same force as a 1000kg car doing 30mph, only it's going to be much more focussed due to the narrow shape.
That sort of impact in the side of a car could kill the driver I reckon
Urm, no. You are forgetting energy is proportional to the square of speed.
A 200kg bike at 160mph has the same energy as a 1000kg car at 72mph. A 200kg bike hitting a car at 160mph would be devastating to all involved.
