Radar Changing the Face of Cycling
First time accepted submitter Franz Struwig writes "MAKE Magazine has a great review of a bicycle radar product — showing off some of the early prototype innards: "The latest version features a 24 GHz radar antenna — high enough to resolve more targets and small enough to fit on a bike — an ARM processor, and Bluetooth LE to communicate with the front unit. The radar creates a doppler map, and recognizes not only the vehicle, but how far away it is and how quickly it’s approaching. It communicates this to the cyclist by a system of LEDs, and to the car by increasing the rate at which the tail light blinks as the car gets closer."
Otherwise, what's wrong with using the eyes?
...is to stop mixing cars with bicycles at all.
That, and do something about the assholes on bikes that think that little white line and bike lane are some sort of magic force field that protects them from massive hunks of steel inches to their left...
If you've got a known medical condition that renders you suddenly incapable of safely driving a car without warning, then maybe you should let someone else drive?
You're a temporary arrangement of matter sliding towards oblivion in a cold, uncaring universe
