Sorry I don't see your point at all. You can manually put the vehicle in 1st gear and drive down the highway and break all kinds of things, you can drive down the road with the rear hatch open and things in the back would fall out, you can use a brick to keep the accelerator at a certain speed instead of using cruise control, you can drive down the road with the hood partially shut with the safety catch instead of shutting it all the way, which would surely end up in a wreck, you can put mismatched tires on and probably damage a lot of components, you can drive down the road with the mirrors folded................... The point being Toyota didn't specifically design it to allow you to do any of them........ but why in the world would you do any of those things.
