    If I have a car barreling towards me, my first instinct is to get out of the way.

    What I don’t think I about, but is pretty important are; A) is the driver doing to respond in time to slow the vehicle? B) is the driver assistance system going to respond in time to slow the vehicle. C) is the vehicle braking system going to be effective enough to slow the vehicle. D) how much momentum (Mass x Velocity) is the vehicle going to pass onto me when it hits me. E) where will my head hit the car when it does hit me. All these factors come into effect in modern vehicles.

      A and B are irrelevent as that goes for all vehicles. C Australian regulations require all passenger vehicles are tested to an identical standard. Heavy vehicles are tested to a different standard but thats only ones over 4.5 tonnes (thats more than a Humvee). D Damage to a person is based on the Force which is accelleration times mass. Momentum is a measure of a bodies resistance to change in velocity as i said earlyer a small vehicle and a large vehicle have so much relative momentum compared to a person you will make very little effective change. E thats the only good point u got.
