Do Alternatives to Seat Belts & Shoulder Straps Exist

There should be alternatives to seat belts and shoulder straps that provides adequate safety. I've thought of two curved, padded  bars emerging low from the sides of seats curving up over the shoulders rather like those of some theme park roller coaster rides. It is the case that some don't like the shoulder strap crossing near the neck, so perhaps its time for the auto industry to invent and upgrade new safety restraints for cars.

I have wondered if any of those safety cameras in newer model cars can take photographs too. It might be useful to taker a picture of road rage or tailgating drivers.
