You're assigning decades of infrastructure costs to AVs, none of which was done with the intention of supporting them. They'd work fine on 1950s roads.

The global AV industry has taken roughly as much funding as California HSR has on its own, and less than what HSR will need to finish.

I've been doing public transit advocacy for my entire adult life. I've worked in the AV industry somewhat less than that. My advocacy has produced a couple of bike lanes and bus stops, contrasted against 3 AV launches.

I'd love to build more public transit, but experience tells me that the most effective thing I can do to support my community is AVs.
