The only stuff that actually matters is keeping people from being squashed and the occupant's deceleration profile which you can already customize by changing how the car deforms. To really make a difference vs a high end car we could mandate 3 point seat-belts and helmets like you have in racing world.

Still a 70MPH a head on collision is already fairly safe assuming people are belted the real killers are unbelted passengers, collision debris, and rolling. Edit: Head on collisions still kill a lot of people but they tend to be higher speeds accidents and often involve unbelted individuals. Also we are slightly below 1 death per 2 million hours in a car we just spend a lot of time in our cars.

PS: Worldwide it was estimated that 1.2 million people were killed and 50 million more were injured in motor vehicle collisions in 2004. http://en.wikipedia.org/wiki/Epidemiology_of_motor_vehicle_c...
