Many people are afraid of riding their bicycles on busy roads. A device invented by a British design student, could help level the playing field a little. Its called BLAZE, and it alerts drivers to the presence of a cyclist by projecting a laser image onto the road in front of the bicycle. Emily Brooke designed BLAZE in order to get those cyclists seen. The device mounts on the handlebars of a bicycle (or a motorcycle or scooter), from where it shoots a bright green sharrow (shared lane) symbol onto the road, several feet ahead of the cyclist. That symbol is visible even in daylight, and can be made to flash on and off. -GM
