In my first start-up, I didn't get any salary for four years, so I had to move back with my parents.

I spent a disproportionate amount of my time in a car in L.A. I'm 35 years old. If you add up the hours spent in cars, it would be years.

Safety is number one at Uber... so we make sure the system is in place so riders get the safest ride possible.
