I call BS too, although I suppose if he was worried about the steering locking he might have refused to turn off the ignition. The throttle on my Nissan Prarie 1.8 jammed wide open at about 75 once when I was on my way to work. I suppose I should have pulled over to the hard shoulder and tried to unjam it but I was late so I just drove it the rest of the way (about 2 miles) using the ignition key to switch the power on and off. I even negotiated a roundabout, and only revved the hell out of the engine once.
