The Wavelengths used are 0.905microns to 1.55microns, while Class A, they are still lasers.

If you happen to be carrying the right sort of material on your skin for example, the wavelength could halve or quadruple. That would locally irradiate you at UV or microwave.

People looking straight at the sensor could get cataracts or irritated corneas.

Its unnecessary technology exposing everyone around it to new unknowns.

Not exactly how that works. But go ahead.

Except for people just walking around getting irradiated at a high enough level to provide feedback for the taxi’s radar. I assume people will start getting cancer… The cancer levels might be funny like 98% on people’s left side or maybe only on people who walk on the sunny or shaded side of busy streets.

I’d give it a few years for the cancers to start showing up.
