I don't think I have ever felt "unsafe" from any of my pax. If I did get a bad/off feeling about someone I would definitely not pick them up or I would end the ride and let them out.Seriously? Ask yourself if you would let these people in your house where you are safe, secure, & insured! If your answer is no, stop letting them in your car.
I made $4 hr last week after being ripped a new one from uber's guarantees. No Drunks! No uber!
