I agree that true AV is way off but it seems like there’s a huge amount of good with partial systems (e.g. continuing to improve auto-braking to deal with inattention) and it’s not inconceivable that you’d see some popular retirement destinations (e.g. much of South Florida) do something like designated lanes for AVs (passenger or delivery) where you could simplify the problem and have things like weather/hour restrictions.

Retirees tend to avoid rush hour and bad weather, and they’re less time constrained, so there’s some room for experiments and there will be a growing incentive as more Boomers become unsafe to drive but are unwilling to give up a key part of their self-identity & lifestyle.
