I am not expecting a performance but I do expect to be picked up where I dropped the pin, I expect the driver to follow traffic laws, I expect the driver to not make abrupt turns because of traffic. So yes most rides are not perfect, I don't know what city you use Uber in but the ones I do the drivers are far from skilled. Frankly, this is one reason why I feel safer in a taxi is the driver in my experience much more skilled at the job of driving.

The Uber driver who just moved to the city and doesn't know his way around without Google maps is going to have a difficult time in major metropolitans.
