I've seen the kevlar blankets, they seem like they would be pretty universal. I'm surprised they couldn't be placed to help protect the driver in a FWD.

I did see an RX7 turn into shrapnell once, or rather I saw the result. While doing something like checking timing in the paddock (not sure what he was up to) the throttle jammed open. Everything stopped only because the flying pcs severed a fuel line, which subsequently caught fire and burned up most of the car. The driver was not so lucky, broken jaw & ankle.

The other moral of this story is that fire & rescue are set up to respond much faster to track incidents than paddock fires.
