The article misses one important point about LiDAR. Frequency modulated variants, referred to as "FMCW", get velocity information for free via the doppler effect. You can't get that information from a camera without sophisticated image processing, and you can't get it with high resolution from RADAR. Knowing velocity as well as position is important to assessing immediate safety threats. There's a good write-up by the co-founder of SiLC, a silicon photonics LiDAR startup, here: https://www.photonics.com/Articles/Integrated_Photonics_Looks_to_Advance_Safety_for/a64791 https://www.photonics.com/Articles/Integrated_Photonics_Look...
