No amount of safety system will save you in a 60mph crash.

  1. People survive crashes at highway speeds in the US literally every day, at 60mph and above. 2. 60mph is a speed not a force imparted on a vehicle. The way with which a vehicle’s momentum at 60mph is dissipated makes a critical difference to the crash energy imparted on the occupants. Road design has greatly improved this in recent decades. 3. Active crash prevention/mitigation systems can prevent 60mph accidents from happening or improve their outcomes.

Yes, but that doesn't count as surviving the crash > 60mph is a speed not a force imparted on a vehicle. The force imparted on you in a 60mph crash by the seatbelt will be lethal no matter how much deceleration space you have. You got at 27 meters per second, and you only have at a maximum 1 meter to decelerate. And if you crash into a heavier, faster vehicle, it's even worse.

And if you crash into a heavier, faster vehicle, it's even worse. Most vehicle crashes are not head-on incidents. Improvements in road design have affected the proportion of crashes that are head-on. Recent improvements in active safety features may decrease this further: eg. lane departure mitigation. In many real-world accidents, vehicles have dozens or hundreds of meters to decelerate.
