They're bad for your cars. They're dangerous to cyclists. In cities, potholes are not just annoying -- they're everywhere. Here in Richmond, our roads have more holes than swiss. Joe Ling is a graphic designer in Norwich, United Kingdom, who has thought up a simple way around this nuisance. These brightly colored floor posters are placed over potholes in popular cycling areas, making them hard to miss. Leaflets under tyres, posters on bike shelters, and hashtagging #ivebeenpotholed contribute to maximum public exposure and awareness. Pretty neat.
