Don't leave your phone on accident when leaving your ride. Their instructions on their help page FOR leaving your phone in the driver's car AFTER leaving your ride is to contact the driver through the app. But when logging in to the app on someone else's phone or through the website, they ask for your phone number, and then the verification code they just sent to your phone. BUT YOU DON'T HAVE YOUR PHONE. I only got my phone back by calling it repeatedly from a friend's phone. Bad design.
