Which competition are we talking about?

GM Supercruise is the only other thing on the market that is comparable, and with Nav on Autopilot I'd argue Tesla is a fair bit ahead.

Maybe they are not ahead of Waymo, but can you buy a Waymo? If not then when will you be able to?

There is Comma.ai which I am impressed with and think will be the general autonomous solution to many (most?) non-Tesla cars going forward, but their product at the moment is for hobbyists and not consumers.
