<div>radar or maybe rfid would work, but it would take some doing to integrate with gps. as another commenter stated, gps is read-only. you're talking about sort of a mashup or overlay of live object tracking and static gps maps.</div>
<div><br class="webkit-block-placeholder"></div><div>at that, this idea would only work for people who have the technology in their cars.</div><div><br class="webkit-block-placeholder"></div><div>so, the simplest approach still is to be visible and ride defensively. periodic driver training courses would probably help, too, but i doubt any political body would pass such measures.</div>

was using radar or somesuch to detect moving objects and then use the<br>already in place gps systems to announce that you were approaching a<br>very slow moving object (or heuristically a cyclist/pedestrian/animal).<br>Such systems already exist in various forms for high end cars to alert<br>
primarily for deer (or at least that's how it's sold, the market for<br>this kind of car is likely to live in their mcmansion in the middle of<br>nowhere and commute an hour to work).<br><br></blockquote></div>
