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.

Do you think that a shared AV model that reduces or even practically eliminates barriers to widespread, impromptu ride sharing could potentially reduce traffic congestion? Given the sheer number of SOVs, even a relatively small increase in carpooling could be impactful.

Double bay bridge capacity, and you still don't get what BART does in peak hours.

Totally agree. Not saying we should abandon BART; just that if people are converted from SOVs to shared AVs that could provide immense congestion/emissions benefits.

We already have the much maligned tech buses. Ride pooling depends on some degree of destination comonality

The viability of Lyft line and the sheer number of people driving into and out of downtown job centers on any given day would tend to indicate we already have pretty good though not universal destination commonality. With greater use of TNCs over SOVs this would work even better.

SOMA back-up w/ Lyft/Uber usage *feels* pretty congested right now. I would like to see studies on this.

I think we're at a point where costs mean that individual vehicle ownership and resulting SOVs make more sense than ride-sharing for many commuters, but AVs and congestion pricing could change that.

Kim, your first point is right though: costs for "traditional" mass transit is prohibitive. AVs+ride sharing are the only way forward. "Contractor Capture" of large projects kills new massive public projects.
