Where I live I am often surrounded by Waymo vehicles... is Lidar 100% safe for people to be around? I ask because I read an article about how Lidar on one of the new Volvos could destroy your phone camera if you pointed it at it? If Lidar can do that to a phone camera, can it hurt your eyes?

Depends on the type of LIDAR. LIDAR rated for vehicle use is at a wavelength opaque to the eyes so it hits the surface and fluid of your eye and reflects back rather than going through to your cones and rods.

It isn't however opaque for optical glass (since the LIDAR has to shine through optical glass in the first place) so it hits your camera lens, goes straight through, and slams the sensor.

During the presentation, Rivian speaker specifically said it is safe for your camera sensors. Check the youtube video of their presentation

Ah. Theirs may be then. In which case they are probably using a different wavelength and a different glass.

I was just speaking in terms of the commonplace LIDAR solutions for road use.
