I've got something to add about roll bars and HANS deices...

It's very true you DON"T want a roll bar in your car unless your 'melon is inside a brain-bucket'. Or invent a better roll bar hidden behind something compliant (available roll bar padding doesn't make it, BTW). In order to help the passenger, you need to absorb any impact over a greater time-space and over the largest area possible (think about the waterballon toss winner's technique at the church picnic).

Maybe the driver and passengers need to dawn an individual air-bag suit. Slip on these coveralls, plug this connector into the car's safety port. You could taylor one for the individual. Close your eyes for a minute and imagine an accident victim looking like the Michelin Man 20ns into a crash

I attended a safety seminar put on by GM at a race a few years ago, the engineer was gushing about the HANS device (and rightfully so). He showed a specially made ultra-high frame per second video of a NASCAR driver experiencing a minor side hit. When they slowed it down and decontructed the footage frame by farme, the driver's neck must have stretched 6" in the incident!
