Guess I'm weird, I don't mind the lap belt and can tolerate the early 80's pull to relieve tension type. But those newer vehicle constant tension restraints make me feel as though I'm getting an MRI every time I get behind the wheel. Tough call on older vehicle, collapsible steering and flexible shaft on 68 or newer steering but no one seems to worry. They showed us photos of impaled drivers back in they days of drivers ed. Seem to remember that none of the belts are attached to the frame only the body. Have heard many stories for the good or bad of them, in the end it's up to the owners.
