Seatbelts

[Crash Test]

When you look at seatbelts compared to other parts of the racing car, they really haven't changed that much over the years. Ok, the material would be of better quality these days, they are 3" wide, the fastening devices would be better, and we've figured out how to position them as to not break bakes in an accident. But the idea is still the same.

What sort of things do you think might improve safety in this most elementry of devices?

This may be completely moronic, but I've wondered for a while if there is any merit in a restraint device like those on rollercoasters. Not completely fixed like rollercoasters, but something that would give a little in a crash. With the invention of the airbag and HANS device, the technology to make something like this would probably be in place. Anyone has any thoughts on this, or a phone number for a mental institution?
