They're building TOD's because they can make much more money right away (by selling land to developers).
Blue Ocean 2012 Leaf SV, lost that 1st bar at 34 months/26,435 miles. Lease returned 2 months later. Final LeafStat figures: 225 Gids, 17.44 kWH, SOC 91.89%, SOH 82.36%, 69.49% HX, 54.57 Ahr, battery temp 61.8 F.
Now driving a 2015 VW eGolf SEL.

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/2019/0 ... tiago.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.

And one more. GCC:
New analysis suggests Uber adding significantly to pollution and traffic in European cities
https://www.greencarcongress.com/2019/1 ... -uber.html

. . . In France, which liberalized the taxi market in 2015, the number of reported PHV drivers doubled in three years (from more than 15,000 in 2016 to 30,000 in 2019). The number of Uber drivers in London almost doubled in three years (from 25,000 in 2016 to 45,000 in 2018), accounting for roughly half the total PHV licence number.

This has made Uber one of the biggest taxi services in Europe, with 3.6 million users in London in 2019 and with 2.7 million users in France in 2017. According to company documents issued for its stock market launch, Uber is looking to increase massively its operations worldwide and is eyeing Europe in particular, identifying Germany, Spain and Italy as priority markets for expansion.

The number of taxi licenses has been capped through licenses; however Uber has seen rapid growth. Since Uber’s arrival in London, its biggest European market, taxi and PHV trips have increased by roughly 25% in the capital. This data strongly correlates with a 23% increase in overall CO2 emissions for the taxi and PHV sector in the UK in the same period.

The analysis estimates that in London and Paris alone, the emissions of Uber taxi services could be as high as 515 kilotonnes of CO2—more than one half a megatonne. This is equivalent to adding the CO2 emissions of an extra 250,000 privately owned cars to the road.

These kilometers have predominantly been driven by gasoline and diesel cars, exacerbating the air pollution crisis in European cities. French government data from 2017 show that 90% of the registered private hire vehicles, which includes Uber, were diesel cars.

The high share of diesels in the PHV fleet can be also found in the traditional taxi market. It’s thought that other European cities where Uber operates have similar levels of diesels in their fleet. . . .

The findings confirm that cities in Europe face the same challenges as American ones, such as New York, Boston, Chicago, and San Francisco, where Uber and Lyft have been shown to exacerbate pollution and congestion.

A broad coalition of green NGOs in the US, Germany, France, the UK, The Netherlands and Belgium has just launched the #TrueCostOfUber campaign. This collective action aims to tell concerned citizens and city authorities that Uber needs to clean up its act in order to operate in cities across Europe and the US. The company therefore needs to help their drivers switch to zero-emission cars as it is already doing in London due to the ultra-low emission zone in the capital.

The campaign in Europe calls on Uber to go 100% clean in large cities by 2025. . . .

Transport represents more than a quarter (27%) of Europe’s total greenhouse gas emissions. Cars emit 44% of transport emissions; these are still rising.

GCC:
CARB: ridesharing vehicle fleet CO2/PMT in 2018 approximately 50% higher than the statewide passenger vehicle fleet average
https://www.greencarcongress.com/2019/1 ... ngco2.html

. . . Among the top-level findings and estimates:

  • CARB staff estimates that the 2018 TNC vehicle fleet emitted 301 gCO2/PMT, approximately 50% higher than the statewide passenger vehicle fleet average of 203 gCO2/PMT.

    The analysis indicates that the industry-wide TNC fleet has a 7% lower passenger occupancy than the California statewide passenger vehicle fleet.

    TNC vehicles operate approximately 61% of its vehicle miles traveled with a passenger in the car; the remaining VMT are deadhead miles.

    The 2018 average fleet occupancy for the TNC industry is 1.55 (an average of the occupancy in “pooled” and “non-pooled” rides) passengers.

    The TNC fleet is relatively more fuel efficient than the California fleet due to having higher fraction of newer model year vehicles and higher percentage of passenger cars versus light trucks.

    Total 2018 TNC fleet electric VMT (eVMT) is about 33.7 million miles—roughly 0.8% of the total VMT generated by the TNC fleet.

    The TNC fleet has a larger fraction of high-mileage hybrid vehicles as compared to the average California passenger vehicle fleet.
Although the vehicles employed by TNCs make up 2.5% of the vehicle population, they are growing at a rapid pace. . . .
