I don't even know what areas of the United States I would consider "walkable". I live in San Francisco, don't own a car, we have "pretty good" public transit, and it's still absolutely miserable getting around. It takes me 40 minutes to go from Outer Sunset to downtown by muni. There are many locations in this city that I can physically jog to faster than public transit.
I can appreciate this technology might negatively impact other countries more heavily, but, for me, it's easily the most exciting tech I interact with and I'm rooting for it whole-heartedly. I'm at around 1000 miles logged on Waymo and am part of their beta tester program for freeway usage.
I also think that post-Covid remote work has probably damaged incentives for increasing the density of cities more so than anything autonomous vehicles will do. San Francisco is actively cutting bus routes, bus density, and threatening to significantly cut BART stops due to budget constraints and reduction in ridership.
It's odd because I do get where you're coming from, and I feel like I should be your target audience, but, for me, the ship sailed so long ago that I struggle to relate to your position.
I think this thread conflating between walkable and having good transit. A walkable city means almost everything you need is within walking distance. That doesn’t mean there are buses or trains to take you out of this area. I live in a walkable part of the city. Within a 15-minute walk, there are three supermarkets, perhaps twenty restaurants with different cuisines, four pharmacies, one each of USPS/UPS/FedEx for shipping, four different banks, three dry cleaners… you get the idea. The only transportation tool I need is my two legs.
Now of course sometimes I’m not content staying within this 15-minute circle. Then I simply choose the fastest method of transport to get there. Is BART or Muni faster than the Waymo trip? Then yes I’ll take pubic transportation. That’s what good transit is for.
You exemplify the defeatism that the auto makers are counting on.
I literally have never owned a vehicle in my life. If you feel I exemplify defeatism then I think you need to look inward.
