AVs and public transportation are not comparable. The cumulative lifetime investment in Waymo would not fund even half a year of capital expenses for the New York MTA, for example.

I'm not sure that's a fair comparison. The most expensive part of self driving cars is building the roads and highways. Would make more sense to compare Waymo to the operating expenses of PT, hiring the drivers and maintaining the trains.
Building roads for buses are _few orders of magnitude more_ expensive than roads for cars only.
Unfortunately we still have trucking, but it's starting to feel we should build separate roads for them and for special cases only allow multi-axle delivery trucks on normal roads.
You’re right, we should!
We could even build these special purpose, heavy duty roads out of something stronger than asphalt, like metal. Then once we have these sturdy new metal roads for trucks, we can raise the weight limit to allow them to carry heavier loads. And since there’s no little cars getting in the way, we could even group together multiple trucks going in the same direction for better logistical efficiency.
You can see where I’m going with this. ;-)

You are suggesting that we should attribute a fraction of the costs of our road building and/or maintenance under autonomous vehicle development? If so, what fraction are you proposing?
No I'm not suggesting that. I'm suggesting that if the proposal was to spend less on self driving and more on public transport, we should be looking at the running costs of PT. Rather than comparing Waymo to digging tunnels or laying tracks, considering we didn't factor road building in the Waymo costs.
