There's also the other side of the problem that you don't get to see as a passenger. Uber/Lyft drivers in a rush to get to their pickups drive like maniacs here in SF. I'm from a developing country and I'm used to drivers who disregard rules but even those pay attention to the surroundings - you can read them and know if they are going to yield or not. But having gotten used to the polite driving of SF a few years ago, I find it quite dangerous to walk my dog out now. I stick to interior roads and wait till I know for sure that the car would yield for me before I cross. Driving and Biking have become usually miserable as well.

My only request is that passengers don't encourage this by blindly rating everyone 5 stars. Take at least two star off for unsafe driving - not stopping at a stop sign, not yielding to pedestrians, not giving enough space while passing a bicyclist and at least one star for not following the rules - driving on the bus lane, double parking in the middle of a busy road, driving too fast on a 25Mph zone, not waiting long enough for the pedestrians to pass safe ...etc.

If the economics don't work out for the drivers, the fare has to go up. By keeping the fare artificially low and pushing drivers to accommodate too many trips Uber and Lyft are ruining the experience for everyone and in doing so are perpetuating the need for more people to use them instead of considering alternate transport modes. This, sooner or later, will ruin it for everyone.

Take it from me, America cannot handle a developing country style traffic. It requires a different set of skills. People here are used to predictable traffic.
