When I see a bike I try to stay as far away as I can because you don't know if they're going to come out in front or if they're going to turn or brake. So the idea occurred to me to have a piece of equipment that alerts drivers when they're going to come out in front, when they're going to brake, to alert those people behind them as to what they're going to do. So it's a language for cyclists and drivers who can get along.
