"TNCs had little impact on congestion in the western and southern San Francisco neighborhoods."

Recently Supervisor Peskin apparently reached a deal to impose a "net fares" tax on the TNC's. I wonder if they will consider differentiating it by neighborhood: imposing larger charges downtown. Peskin has also lobbied for downtown congestion pricing although that is harder to implement, politically and technologically, than such a tax.

“TNC information was based on data originally gathered by researchers at Northeastern University from the Application Programming Interfaces (APIs) of Uber and Lyft that show the locations of available vehicles to mobile apps, and then was shared with the Transportation Authority.”

Why would they use such a terrible data source. I had always assumed the cars in the Uber map are indicative anyway, not the actual location. Uber gives trip data to cities why not get real data

The issue with conclusions of reports like these is that yes, Uber/Lyft contributed to a congestion increase, but what would that increase have looked like without Uber/Lyft? How much would congestion have increased by without Uber/Lyft (due to the strong economy, jobs, etc)?

Would people instead have purchased cars and driven them around instead? Would we actually have had higher congestion?

Publishing reports like these without controlling for the economy/jobs/popularity of these cities seems to me to be an unfair attack on Uber/Lyft, where the real culprit might just be a strong economy.

How exactly would you control for all the rest? Where is there another San Francisco that doesn’t have Uber that we can go measure?

I think these estimates pass the sniff test at least. Downtown SF has very little parking relative to demand, so Uber / Lyft are practically the only way to get there in a car.

I guess your assumption is that every one gave up on buying car and instead every day they drive to work. The impression i have from my friends is different: they use lyft when they cant take car or want to drink while with strong economy the can afford having car as well. I dont know any single person who would sell their car because they can travel with lyft to work every single day.

Really? My experience has been extremely different, albeit both of us only really have antidotes.

My friends/coworkers who got jobs in the city directly after college all don't have cars. Think 2013-2018 graduates. The only ones with cars, either grew up in the bay, or have worked outside the city at some point. Mind you these are all people who have a license in their prior state/country.
