1) how many hours does a pilot need on a 'type' to fly unsupervised?

2) it seems kind of a meaningless unit here, because nobody said it was real world real-time driving hours? And even if it is, if they were logged with the intention of finding 'interesting' scenarios vs. just A-B motorway driving would make an enormous difference.

Excellent question. And the answer is between 45 hours and a few hundred million years. Hear me out.

45 hours is because that is the minimum amount of flying you need to get a private pilot licence: https://www.takeflightaviation.co.uk/ppl-guide.html

(Ignoring here ultra lights and paragliders where you sometimes don't need a licence in some jurisdictions.)

So that is the straightforward answer maybe you are looking for.

Then we might say that all pilots are required to be at least 17 years old to obtain a private pilot licence. So that is 148920 hours of pre-training in preceiving objects and movement, and coordinating one's actions with perception.

Then one might also say that one requires to be a human, and that comes with hundreds of millions of years of pre-training where all of our ancestors were evolutionary selected to be good at perceiving and moving. (At least good enough to survive until they could propagate their genes.)

Now this answer might come of as flippant, and maybe it is. What I'm trying to say is that it is hard to compare "training hours" directly between computers and humans. And it is hard because of these two things which humans have "pretraining by lived experience" and "pretraining by evolution".
