I know the videos have lots of room for improvement. My cams lack image stabilization. If I raise the camera angle to show the scenery, the cockpit instruments are underexposed. If I mount the camera solidly to a window, it vibrates too much.
The brake thing is easily handled by restarting any time you've used the brakes, and avoided by better planning so you won't need the brakes. Then again, I can't speak for anyone else but I have plenty of leg strength to operate power brakes that have run out of assist, though I wouldn't want to try to modulate them in a race or pump them in an ice/snow situation without assist.
There's also the lack of power steering, which is much worse in a car with power steering than one with manual steering, and there's nothing that can mitigate that. Even with gorilla arms you will be unable to steer as fast as you can with assist (or with proper manual steering equipment).
If you're going to EOC (Engine-Off Coast), know that it is dangerous and most likely illegal. Do it as safely as possible on unpopulated empty roads, if at all. Be ready to restart at any time and don't be shy about it.
You can never be sure what's around the next bend, and if you need to use your steering/brakes swiftly in an emergency, when you have a millisecond to react, you're going to be doomed! Don't risk it, just be grateful that you don't live in the UK where fuel is $8 a gallon.
