Leaving a music festival outside of Austin in 2014, I remember pulling up my Uber app to book a ride back to the city—but thousands of other festival-goers around me were doing the same thing. After many failed attempts later, with no alternatives to make the nearly 20-mile journey back so late at night, I took a risk and piled into a car with a group of strangers. Thankfully, I was dropped off at my hotel safely.
