Crash tests

does anyone know at what speed these tests are done at i heard 30 mph in the videos it looks faster

The IIHS offset frontal impact tests are done at 40 mph, and their side impact tests are done at 31 mph.
I suspect that no vehicles would pass if the side impact test was done at 40 mph.

Out in the real world, at 80 MPH, everybody dies no matter how many air-bags it has.
