@franciskim TNCs (e.g. Uber, Lyft) increased VMT. One of the “benefits” of AVs is that they remove the human driver (so lower cost and no obligation to speak with, or feel guilt about, a human). AVs will increase VMT. https://t.co/KQY5WKu3eH https://t.co
@DumasRaphael Pre-pandemic, one ridehailing trip (in Denver) carried an average of 1.4 passengers. Including deadheading, average vehicle occupancy was 0.8 pax. Not sure about taxis or more recent research, but this is a pretty well-accepted number as far
@SierraIguana @mims Yeah I would anticipate a fair amount of variance there by location. 40% is what I recalled from some study, but this study in Denver says it's *85% more*, and that's after controlling for mode replacement. Ridehailing is an enviro-nigh

Hailing rides - via Lyft, Uber etc - increases vehicle miles traveled and subsequently emissions studies find.
Wow, this is a serious impact: The use of Uber, Lyft, etc. leads to more than 80% extra vehicle miles per trip (compared to the situation that these services had not existed). Limited data yet, but nevertheless alarming results.

Convenience for oneself doesn't translate to anything other that in many cases. Taxis are destabilized with unions and benefits sidelined, and now this. There's no upside to ride-hailing.
