Light Lane brings Tron to the Streets (oh, and would probably save lives too)

Bike lanes have proven to be a safety boon for cyclists, but an expensive outing for cities, and a crap shoot by night. Alex Tee and Evan Gant of Altitude have dreampt up an idea that takes the concept of bike safety out of the tax-payers hands.

Light Lane projects a crisp, laser-defined virtual bike lane onto pavement, thus adapting the riders instead of the roadways. A projected bike land wherever the cyclist travels gives drivers a clear indication of spacing much better than static safety lights or mere reflectors ever could. According to the designers, "with a wider margin of safety, bikers will regain their confidence to ride at night, making the bike a more viable commuting alternative".

Sadly, this is one of those designs with a demand but no supply. Yet.
