My post has nothing to do with braking,
but I have been in a serious crash in my '94 Dodge on the rear quarter which spun us around almost 360 degree, basically a front wheel becoming the pivot point and rotating around.

I was suprised to find the engine had stopped running.

Also, our previous Grand Caravan was T-boned on the passenger side sliding door and we rotated about 180 degreese and pushed us about 20 feet. It was a real hard impact and the van was totalled.

Once again I was suprised that the engine stopped running. (And everyone was OK)

I guess crash sensors shuts the engine off in those situations.

Efficient drivers do it better.
