like hacking game consoles, i expect the manufacturer to void any warranty, and try to ban your vehicle from any updates etc (other than recalls and items of safety nature)?
would ICBC be "OK" with you "modd'ing" your car's software/main processor? even if it was completely safe i can't see an insurance company wanting to touch that with a 10' pole and just say "nah - claim denied"
if they sell their car as "base" at a base price, and then offer all these upgrades for fees, maybe there's a market for that ala carte method.
but i can see them being greedy as fuck and pricing their cars above base AND wanting a piece of this pie...they'll fuck it up i'm sure
