I watched it last night. They remote drove a Suburban truck and Airstream trailer down a hill with no brakes
, just downshifting to slow it like when your brakes
fail. It ended up the combo flying off a hill and crashing. If they would have used one of our lightweight trailers it might have slowed down in time. Putting retro-rockets on another Airstream was not a good idea either with a lighting
of the rockets when they were trying to arm them. I've had a brake failure before on a steep downhill in the Sierras with a Toyota motorhome with manual transmission and was able to bring down from a runaway with shifts into 2nd and 1st gears. It will definatley get your atention when the pedal goes to the floor!
