If you think about it, renting a car is one of the least-surprising parts of travel. You wait in line, hand over your credit card, get your keys and are on your way. No matter where you happen to be—Dallas, Los Angeles, New York—the process is pretty much the same. Enter Silvercar, a new concept in the car rental game with a design identity to match its innovative approach. You see, every car the company rents is silver (at the moment only 2013 Audi A4s) and every step of the process can be done via smartphone, from reservation to pick-up.
