The thrust that you get is NOT a normal thrust. I know it's hard to understand, but what you get is asymmetrical thrust. This means that if your left front tire is flat, and you leave the cruise control ON, or 'stomp on the throttle, either way you are getting, or you will get, more thrust on the left side than on the right side. THIS is what helps the motorhome steer away from the flat tire side. The reason this is hard to understand is because very few drivers know exactly how the differential gears in the rear axle work. Have you ever wonder why it's called "differential"?
That's why I said that when/if I have a front tire blowout in my motorhome, while driving down the highway, the first and most important thing to do is instantly steering-wheel STEER the vehicle. And, I do NOTHING with my feet. In cruise control, it instantly will asymmetrical thrust on the side that I want. This is a concept that takes a lot of words to explain correctly.
Sure, Cat 320 was able to simply control his motorhome with just the steering wheel. I can believe it, if he didn't immediately go for the brakes.
In the MIchelin (John Anderson) video, it could be that he chose to instruct drivers to stand on the THROTTLE,....maybe he decided that it was better to keep his instruction simple and not complicate it with whether or not the cruise control was on. What do you think?
