When I worked in San Francisco I took Caltrain to the city, but I took Waymo from the train station to the office. San Francisco, like almost all US cities, has poor local transit coverage. In my case there was a bus that took a similar route, but it only ran every 20 minutes even during commute hours and wasn’t coordinated with the train, so if everything was running on time it would have been a 17 minute wait (plus an extra 5 minutes walking). I was busy and well paid enough that spending the extra $10 to save ~20 minutes of travel (and the uncertainty of when the bus would arrive, and how strongly it would smell like piss) was well worth it.
That the load bearing part right there. SF's transportation is pretty piss poor
Damning with extremely faint praise there...
According to [2] Uber drivers make $15 to $25 an hour, before expenses like fuel.
So while it's not normal it's certainly plausible that some people take taxis on a daily basis.
More broadly, as levels of wealth inequality rise in a given society, more people end up working in the personal service sector doing things like cleaning, food delivery, taxi driving etc.
