I bike commute in San Francisco and on a typical day I dodge literally dozens of illegally double-parked ride share cars occupying marked bike lanes. I have been nearly doored multiple times, nearly run into parked cars multiple times, been forced into traffic innumerable times, etc.
This is not the 'fault' (sic) of individual drivers. It's the business model, and I hold Uber and Lyft accountable.
EDIT: taxi drivers do this 2% as often; I've bike commuted in the city 20 years and it is apples and oranges
And when I'm on the other side and need to take a cab, I much prefer to take a yellow cab, because they get there faster. Even with GPS, a dense urban environment is filled with little foibles and tricks that only experience can handle
I think that pricing congestion directly would be better, but in the absence of that, this is an example of Uber hurting some citizens who are not taxi companies.
To cite road congestion as being part of the "spirit" of why taxi medallions were created leaves me with the impression of someone being disingenuous.
What on earth makes you assert this? The intense and (to modern eyes) borderline insane levels of traffic congestion in NYC at the dawn of the automobile age are very well documented. There are pictures and videos you can easily find, that make today's horrible congestion look bearable and civilized. A lot of traffic rules and devices have their dawn in the same era.
