Either private ownership, or available as robotaxis etc.

Level 4 or better; if a human at the wheel is required, it won't count for this market

Limited trials may or may not count at my discretion; a service with a waitlist like Waymo had until recently will be counted as long as it's possible for a normal person to get on said waitlist.

The year when they first become available and all years after it that have been added as answers on the market will resolve YES.
