WHY BUMPER? Do you sometimes have frustration on the road because a fellow road user sticks all the time to the left, overtakes to the right or is perhaps driving too close to your bumper? With the Bumper app you can send a complaint to these road users so that they are aware of their poor driving behavior. Hopefully they will learn from it when several people send these complaints to them!
