Tesla is looking to introduce radar back to its vehicles at some form, starting this coming January, according to its own filing with the Federal Communications Commission. It's not clear if it will be a LiDAR for the self-driving suite, or one for the cabin, but the filing says it will be a high definition one.https://www.notebookcheck.net/Tesla-files-to-bring-radar-back-to-its-self-driving-hardware-kit-as-soon-as-January.673147.0.html
Tesla only doing this because in FULL panic mode. Losing HUGE market shares to Chinese EVs, which all use LIDAR.
