False positives from road signs, overhead signs, radar-reflective trash. Commonly used radars have limited vertical discrimination.

- lagadu 8y agoWhy would the radar even be pointed at areas several meters above the car? Maybe radars can't be pointed at a narrow space, if that's the case why not use lidar instead?
- bobsil1 8y agoMost radars aren't coherent like laser, beams spread out. Also radar measures speed more accurately than location. Lidar only used by R&D + taxi services, price not reasonable for car buyers yet.
