Regardless, each driver I met was absolutely fantastic; very friendly and professional. The one complaint all of them had when I asked their opinion of Uber: The GPS is horrible.
One guy was going to make the switch to Lyft JUST because the Lyft maps use Google, and apparently it is simply just that bad.
I did witness this myself while on a work trip this past weekend - Uber GPS led them off the highway and then back onto the highway adding an extra 5 miles for no apparent reason.
