Good points - I mostly agree with most of them.
One thing though is hard to quantify: The wide-spread belief that self-driving is a)
possible at all and b) the arrival is imminent - within a very few years.
There is a cultural/psychological component that may be culturally related, maybe depends how strong your grounding in science and technology is. (Maybe also depends on how much science fiction you have read.)
People got used to Deep Blue beating Kasparov in chess, but it was fairly big then.
For a long time after, the game of Go was the next frontier, until suddenly that was not only conquered, but
vanquished.
Go is *big* in the china cultural sphere - Koreans openly
wept when their world champion Lee Se-dol was roundly beaten in 2016 by 4 games to 1.
Lee was optimistic, nay cocky before the game, thinking that he could hold a master class in go and teach these these arrogant (mostly) Americans programmers a lesson in humility.
He himself afterwords said that the go-program had a 'feel or deep intuition for playing go' that
utterly stunned him. Given that, it is a testament to his mental strength that he recovered form this great shock, and actually won a subsequent game by playing perhaps the best game of his life.
Many people's minds were blown then.
Lee retired in 2019, saying that no matter how good he could still become he could never beat the new 'entity'.

So, for option F) i would add this:
A large number of totally ordinary people waking up to the fact that the arrival of Self Driving might be
pivotal moment, to be compared with other big technological leaps like steam engines, the assembly line, computing or the internet. And invest according to their newfound realization.
I think it will be an iPhone moment.
