The charger/car chicken/egg problem was largely just a matter of "who's going to shell out the capital to make it happen" kind of problem, not really a question of "is this even technically possible given what we have in the next 10 years of development".

IIRC the idea of reusable rockets was mostly considered possible just risky and pointless when the only real customers (at the time) tend to have seemingly infinite budgets if you drag it out of them. SpaceX bet on the reusable rockets and the gamble paid off handsomely, and showed there is quite a market for things when you bring the launch costs down 5-10x. It turns out a lot of people would like to put things in to space at that price point.

A lot of these big achievements are largely having the willingness to throw capital at a potentially risky but otherwise technically seemingly possible ideas. Self-driving cars are not in the same category as EV chargers when it comes to a "can we do this" kind of thing.
