The tip is always call the uber driver first after you made the booking, so the driver wont call the account's number. And never ever book the uber to or from your home/workplace location, select 2-3 buildings away. Anything happen the driver can track your last location (especially if your country/city have a tough law on fraud case).
but I wonder what would happen if the driver got suspicious half-way thru the destination? I mean I look like a non-white local but I booked using let say... an american account? Will he kick me out of the car, or drive straight to the police station?
