Ph.D student Leah Buechley has designed several items of electronic clothing, but her signal jacket for cyclists is, I reckon, something that should be picked up by clothing manufacturers at soon as possible. LEDs embedded in an arrow formation flash to indicate the cyclist is about to turn left or right, warning motorists, and so, hopefully, preventing any unnecessary squishing. The LEDs are powered by that cute flower-like thing in the center of the jacket. It's the LilyPad Arduino, a small, sewable computer chip that was designed by Leah herself. [Leah Buechley via DVICE]
@nutbastard: Agreed on the punishment.
I've felt that what is needed on cars now if a no-turn signal. So you have left, no-turn and right. So many people do not use signals, it's become a guessing game whether the driver is turning without a signal or going straight. the no-turn signal would signify a driver is going straight, but yet is a courteous driver and uses his or her signals.
On the topic of this thread, I would rather see a helmet with in-built signals. If I wore this jacket EVERY time I rode on the road, it would smell like roadkill in a month.
