Ford is developing a seat belt that inflates when the car detects a crash. In The Wall Street Journal, Matthew Dolan writes:
Its inflatable rear seat belts spread crash forces over five times more area of the body than conventional seat belts, said Sue Cischke, Ford group vice president of sustainability, environmental and safety engineering
Each belt's tubular air bag inflates with cold compressed gas, which flows through a specially designed buckle from a cylinder housed below the seat. The inflatable belt's accordion-folded bag breaks through the belt fabric as it fills with gas, expanding sideways across the occupant's body. It looks something like a water wing children wear in the pool before they know how to swim.

High end cars have some great features. They dont cost that much to add. and when they FINALLY implement them on lower cost cars, people say WOW/cool/..
Like Left/right turn signals that ALSO LIGHT UP the direction you are turning, so that you can see CURBS/object in the way. This feature has been around for years, and takes VERY little to add to a car.
LED lights to brighten your displays, RATHER then HOT BULBS that DIE every 5 years.
Make seat belts COMFORTABLE, and people will wear them.
Make them UNobtrusive..AUTOMATIC..and NOT electrical powered(thats hazardous).
It was funny with the original Crash bags, were filled with INERT GAS?? and a FINE POWDER..the powder wasnt INERT. And many have gone back to Corn starch which works great.

As a driver for the last thirty years, and claim-free for the last 20 (350,000 miles or so) I reckon driving style has a lot more to do with staying safe than any number of safety features.
Easy solution, though: plastic clips that allow adjusting the shoulder belt to a comfortable angle. Inexpensive, and at least some auto supply places routinely stock them.
