Stupid article. Lidar can't see lines painted on the road. Using lidar wouldn't have any impact on the described problem.
LiDARs can absolutely detect painted lines and other painted symboles on the road. LiDAR is an active sensor technology that emits a LASER light beam and measurs the reflected echo, using the time delay between emittion and reception (time of flight) to measure distance. The painted lines will reflect the LASER with more intensity than the asphalt and the LiDAR sensor has the ability to measure that as well.
The successful autonomous vehicle deployments all use LiDAR and hd maps and cameras. Tesla is way behind at this point.
