It's not clear to me that 'beta' is, or should be, an allowable thing with regards to vehicles.

As far as I'm aware you're not, legally, allowed to put out of spec tyres or breaks on your car, but somehow a beta feature that can autonomously control a vehicle is okay. I'm not convinced.

Personally I'm not at all fond of the idea of trialing beta features. If you ride the bleeding-edge expect to get cut.
