Perhaps most safety problems. But if you need to outrun an erupting volcano, a tsunami, or the police, slowing down won't really help you.

"... outrun ... the police"

I doubt that this is a use-case that legal, for-profit companies will be pursuing.

For the other use-cases, you can just say: Manual driving only.
