Not to be Cynical,Somehow the article sounded like a sales pitch for "Wavesense". They too want to have pie out in the self driving race. As mentioned in the article, each sensor(Radar,Lidar,Camera) has a limitation on its own. But, Self driving cars depend not just on one sensor but on Fused output of sensor. Also, they use V2V, HD maps and GPS/DR for localisation. Wavesense is another sensor that can solve localisation problem. They too might have difficulty in cases where there are fallen metal objects that reflect different signatures, causing trouble. More the sensors, more the confidence for Self driving. Edit: Grammar & some terminology
