They're building TOD's because they can make much more money right away (by selling land to developers).

Also because it makes sense if you want to reduce pollution/GHGs/incentivize walking/biking/mass transit and dis-incentivize driving, which is why local governments are pushing for them:

Oh sure. They push them as the green thing to do. But ultimately it's about the money, and BART really needs it to fix their aging system.

We've given them a big infusion of funds from various taxes and tolls for that. As it is, they're having issues with their brand new new cars.

Yet another confirmation of ride-hailing effects, via GCC:
Santiago study finds ride-hailing increases VKT
https://www.greencarcongress.com/2019/05/20190520-santiago.html

Researchers from the Universidad de Chile in Santiago, Chile have found that unless ride-hailing applications substantially increase average occupancy rate of trips and become shared or pooled ride-hailing, their overall impact is an increase in vehicle kilometers traveled (VKT). Their paper appears in the International Journal of Sustainable Transportation.

The authors used survey results on Uber use by residents of Santiago, Chile, and information from other studies to parameterize a model to determine whether the advent of ride-hailing applications increases or decreases the number of VKT. They used a Monte Carlo simulation for a range of possible parameter values.

    Our base scenario indicates that ride-hailing applications have increased VKT. This occurs because many trips made using ride-hailing services come from mass transit or are new trips (induced demand). However, as the occupancy rate of ride-hailing trips increases, the possibility that ride- hailing decreases VKT is higher. If ride-hailing becomes shared or pooled ride-hailing, in more than 50% of our simulated scenarios VKT is reduced if mean occupancy rate is 2.9 pax/veh or higher. Thus, the average occupancy rate among ride-hailing users is a key parameter that determines the impact on VKT.
