You Shall Have Bike Lanes Wherever You Go

Some cities are slow getting around to approving bike lanes; others don't bother. Here is a way to carry your bike lane with you wherever you go: project it onto the road with fricking lasers. Alex Tee and Evan Gant of Altitude write:

Our system projects a crisply defined virtual bike lane onto pavement, using a laser, providing the driver with a familiar boundary to avoid. With a wider margin of safety, bikers will regain their confidence to ride at night, making the bike a more viable commuting alternative.

A commenter pointed us to another idea to promote bike safety:

The SPEED-VEST is a bicycle safety device and advocacy tool which displays the wearer’s current speed on their back in easy-to-read lighted numerals. It improves rider conspicuity while legitimizing bicycle speeds on the roadway. Originally conceived by Brady Clark and engineered by Mykle Hansen, it just won the Hub Bike Shop’s Bike Gadget Contest in Minneapolis, MN.
The system consists of a wheel speed sensor, a wearable numeric display and a small computer that does the thinking. The computer is an Arduino: an open-source embedded computing platform powered by an Amtel microcontroller. It runs for 6 hours on a 9 volt battery.
