After each ride, you'll have the opportunity to rate your Driver (and Driver will rate you, too). When requesting a ride, you'll see your Driver's ratings and reviews. The Driver can see your ratings as well. When browsing on social media, you will be able to see your friends' Driver recommendations. This can help you choose the right Driver for you. You can also choose Drivers from your contact list in your phone or from your friends on social media when synced with the CAR app. The Call A Ride in-app social platform has a tab where you can see your friends' and contacts' reviews and recommendations (good or bad) for Drivers they have used. This is just another tool you can use to find the perfect Driver for you. CAR also allows you to "favorite" your Drivers after each ride, so you can use them again and again for future rides.
NOTE: Both Rider and Driver have the ability to give a single reply to any review.
