Flawed locational identification in their GPS map; resulting in dropping the clients in wrong destination even though the rider inputs the right address while booking the Uber cab. This is very dangerous, especially during a night ride, for a newcomer unknown of locational topography of a place, olds & infirms, and ladies.
Very unreasonable surge rates.
Seems to be little control over the cab drivers.
Must have a direct mechanism for the riders to contact local uber control in case of rider being directed to wrong destination.
