Yup. Uber drivers aren't competing against each other for fares or rushing to busy venues to pick up rides. So most of those complaints don't apply to Uber drivers.This is where the inbuilt quality control comes in handy with regard to real-time reviews and 24/7 support. You will have LESS of these problems with uber than you do with cabs.
Uber drivers DO annoy me in that since they have dedicated riders, very often those civilian cars stopped in the driving lane closest to the sidewalks blocking traffic or bike lanes are Uber cars waiting for their rides to come out. That is annoying. But cabs do the same, and in many other respects, Uber is superior. And definitely safer.
