In SF I always use Uber over taxis for the better experience of hailing and paying for a ride. But within the last year I notice every day how bad Uber drivers are severely affecting the city for the worse.
So many uber drivers don't know how to safely park to pick up or drop off passengers without blocking traffic. Drivers don't know the fastest or safest routes to get around with other drivers, busses, cyclists, pedestrians and construction.
I don't want to see Uber regulated to hell, but I would like to see features of taxis required for drivers like signs on top of the cars indicating cars for hire, and most importantly lots more training about road safety.
