110308taxidoor11.jpgAs any cyclist will tell you, one of the biggest dangers of riding a bike is getting "doored," when someone inside a car abruptly pops open a door to exit the vehicle. The potentially deadly situation is often caused by taxi riders who open a door without looking or who try to get out on the traffic side, as opposed to the sidewalk side. Now cyclist and graphic designer Marko Bon is urging the Taxi and Limousine Commission to add a logo like the one seen here to the TV screens in cabs. According to Streetsblog, the commission has shown interest in the design, and Transportation Alternatives has also been pushing for the use of video PSAs to remind cab passengers to open their doors carefully. Last year 66-year-old David Smith was killed on Sixth Avenue when an abruptly opened door knocked him off his bike into the path of a truck.
