It is on the list, and notice I said "mass market" vehicles. No other manufacturer, even today, has as many autonomous cars on the road as them. And the ones that do exist are not as advanced as Tesla's.

These other car companies have had so much more time and resources, and they have not pushed the way Tesla has.

Because Tesla needs to make a lot of money, very quickly. The other makers are already big, and can afford to play it safe. Tesla has to keep risking everything in silly marketing tricks.

They'll cool down in a few years (or disappear).

I think it's more about who is in charge, not how much money they need to make. I don't see Musk ever "cooling down".
