hmm not safe enough for full sized cars, I'd hate to see what that would do to a marshall it crashed next to hahaaha cool stuff though id like to see it go
i did a hydrogen fuel cell car project last year. it was pretty cool.
It would def stop a lot of hacking!!! Pits stops would be very interesting seeing as how you need a high pressure hook-up, and so would marshalling! I wouldn't want that thing flying around a track by my feet! Cool idea though!
