iCall Shotgun by Norm Cramer
iCall Shotgun is a random seat assignment generator for the car. It allows you to enter your riders’ names, configure your car’s layout, and then assign your riders to random seats. You can block out seats that you don’t want to assign, such as a baby’s car seat position. You can also select if a rider is allowed to ride in the front seat or not, and you can even put the steering wheel on the right if you choose (UK, anyone?).
