I love the cruise control and auto drive options. I don't find the default cruise speed very relaxing and appriciate being able to bump it down.

A feature request that, if I were you, I would probably say no to:

It would be cool to have URL flags to load with auto-drive on and cruise control at a certain level.

I think it would be fun to easily share what I find relaxing about this. Also it would be a kinda cool default new page.
