Hardly "modern". We've got one car with electronic injection (1990), two with carbs & stop solenoids (1990 and 1984ish) and as for the rest - I think the chances of "the computer overriding" the ignition switch is, well, minimal.

The crumple zones, body shell, air bags, seat belt tensioners etc must have been absolutely excellent if she survived a 90mph head on crash. Excellent job Toyota - well done. Oh, BTW fuckwit - you 'forgot' to mention it was a 1999 Yaris which has cable operated accelerator Liar, liar, pants on fire. -- Dave - intelligent enough to realise that a push bike is a kid's toy, not a viable form of transport.
