The 1st 5 seconds of that video made my ass pucker.
That is my ultimate nightmare, and the reason I have basically a doorspring on my throttle cable on my Pontiac.
Hard to see in this pic, but I drilled the giant, overbuilt alternator bracket for attachment and used a very stiff dual spring setup- and it's attached in such a way (in line with throttle cable) so there's no excessive load on the throttle shaft, preventing eventual wear.
