Bob - cool cat photo!COOLNESS! I gotta laugh though. I'd like to see how any car would do hitting a concrete wall at 70 mph! Gimme a break (so to speak).
That is incorrect.And you don't have to hit a fixed object at 70 mph; a head on collision between 2 cars at 35 mph generates the same closing speed, although they aren't fixed so there may be some attenuation of the impact forces.
