I've become a lot less impressed with the quality of Uber's drivers and their vehicles as of recent. My last two trips were in vehicles strewn with kids toys and the personal belongings of the driver. The AC wasn't working on the second of these trips.
The first driver didn't like the route the GPS gave him, so I had to use my phone to give him directions the whole way there. I had to remind him to stop the meter at the end of the trop. The second driver seemingly didn't understand how to use his navigation system. Mind that where we were going was a fairly major destination in the city, so there really isn't any excuse for either of these drivers to not know how to get there. This driver also had serious road rage issues, shouting expletives at other drivers on the road. These two trips were easily the worst "taxi" trips I've been on, and they've really tainted my view of Uber.
