GM Working On Wi-Fi Direct-Equipped Cars To Detect Pedestrians and Cyclists 111
cylonlover writes "General Motors is working to expand upon its vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication systems that allow information to be shared between vehicles and infrastructure to provide advance warning of potential road hazards, such as stalled vehicles, slippery roads, road works, intersections, stop signs and the like. The automaker is now looking to add pedestrians and cyclists to the mix using Wi-Fi Direct technology so a car can detect them in low visibility conditions before the driver does."

Why not use heat sensors?
Heat sensors are the wrong technology to use for this. Radar works much better because it can detect cold objects as well, penetrates fog/smoke, and can use the doppler effect to detect if an object is moving. Radar is what the Google Driverless Car [wikipedia.org] uses, and is what most other autonomous vehicles use as well. It is also what most automatic cruise control systems [wikipedia.org] use.

But . . . Can the car warn the pedestrian that they about to get hit ?
We used to have that in cars in the seventies, it was called big V8s.
