Question

What are 3 safety features in a car that are in development?

Answer 1

I have seen reports of better seat belts that go across both shoulders much like the restraints in a race car or fighter plane.

This setup would have have been useful to a friend of mine after a car plowed into the back of his at 50 mph.  The unrestrained shoulder snapped forward after the initial impact causing damage to his shoulder and neck.  Lives in pain each and every day.  Of course if the other driver had paid just a little more attention, this accident never would have occurred.  

We need more skillful, safer drivers on the road today.
