LIDARs can be blinded by consumer grade laser pointers, I wonder if there are systems that protect LIDARs against adversarial attacks or DOS attacks

Drivers can also be blinded by consumer grade laser pointers.

If someone starts attacking safety systems physically I would expect they will get quite a bit of jail time.

They can be blinded by the sun too.

I worked as a reaserch engineer at a uni playing with a 16 beam Velodyne when those were fancy.

Put it on a car for a demo day, drawing the dots in 3d and marking obstacles red, and during sun set there was artifacts with no obvious way to filter out.

Strangely, I was never able to recreate this. I think was some specific athmospheric condition.
