Some people simply don't know how to drive. They should not be on the road. I've had throttles stick on a few things, mechanical links or return springs don't always work like they're supposed to, either. I'm still here, and the vehicles I was in didn't get wrecked.
I had the throttle stick wide open on a top fuel Bonneville land speed record rocket car doing over 550 mph. When I finally got it into neutral it had broken the sound barrier over three times. The power steering went out around 683 MPH but I was able to steer it with Body English. Then the parachutes malfunctioned but I was out of salt flat anyway. Lived to tell about it.
