Also, a discussion here of why it's so ridiculous that it costs *$190 MILLION* to build *TWO MILES* of *BUS LANE*, in reference to the Van Ness project I mentioned in the original tweet:https://www.thebaycitybeacon.com/politics/the-van-ness-brt-costs-way-way-too-much-pedestrian/article_06b07030-c829-11e7-8050-73ea7942d1e2.html …

This is not an argument not to invest in public transit. In contrast, I am *VERY* much a supporter of major investments in mass transit and would like to see a second Transbay Tube on the ballot in the near future. I am concerned that these costs erode public trust and

make voters less willing to support necessary long-term infrastructural investments, which in turn cede more of our systems to private solutions, which can roll out more rapidly but are insufficient in the long run.

Self-driving cars will not address the fact that we have a limited number of bridges in the Bay Area, which have limited capacity and would face an induced demand problem should AVs reduce fares/cost.

But AVs would also increase capacity. There’d be a new equilibrium point at higher volumes. Dynamic real-time road pricing adds another variable, as does having more than one person per vehicle

increase capacity & induce demand. Fixed-line, high capacity mass transit is complementary to AVs & ridesharing, not a substitution. This complementary effect is even more pronounced for large public transit agencies w/ rail. http://individual.utoronto.ca/jhall/documents/Uber_and_Public_Transit.pdf …

Trains have induced demand. All and any infrastructure has induced demand - that’s not ipso facto an argument against it. And on a multi-decade timeline a lot of possibilities for AV blur the difference between buses and cars.

I didn’t even own a car until I moved here - I prefer transit. But autonomy will transtorm road capacity, both because they drive differently (no traffic waves etc) and because they could make many more vehicles multiple-occupancy.
