I doubt you’ll be able to buy a personal level 4 anytime soon, it doesn’t make sense to use them as anything but fleet/taxi vehicles since they can just come to you whenever needed.

I don’t want to buy one; I want to be able to summon one on demand. Same timeline?

Buying a L4 car may be not possible. Because I don't even think they will start selling them initially. May be we can bet on number of L4 cars in operation after 5 years.

Any likelihood of this vehicles being at times(say on the highway) autonomous and at times remotely driven ? Does this work technically , and maybe legally ?

so what's your guesstimate?

Similar background and profession - putting aside whether an individual would ever want to own one, general purpose passenger autonomy won't happen for probably another decade. Limited domain autonomy will be here in before 5 years, though. It'll just suck.

But the first step to getting good at something is sucking at it.

Ish. I still can't do a pointe, even though I've been sucking at it for [redacted] years.
