Re: Assume it was an auto box.
Disabled guy suddenly expected to put in 10x the control input to either break or stop at 200km/h???
what could possibly go wrong.
re: electronic keys: my mondy has keyless ignition (the fob needs to be more or less in the car, for the start button to work) and i recently tested it, leaving the engine running and strolled off with the fob in my pocket - no effect (sensibly - imagine it got carelessly chucked out of the window on a motorway)
havent tried pressing the start button while moving, but i would not be at all surprised if that had no effect either.
(note to self: try giving the start button a prod the next time you are on an otherwise deserted road)
