Humans do not have a light source and use the Sun's light. This is why we see in the "visible" spectrum.
If you can bring your own well collimated coherent source you have no reason to stick to visible light. On the contrary, other spectra might be better (lower background noise, easier to produce coherently, easier to direct, etc).
- yathern 10y agoWhile I agree with your points - I would say to the contrary that roads are currently marked-up for visible spectrum usage. Road signs and lines are made for consumption within the visible spectrum - some of which may be able to be seen in other light. Though possibly an argument could be made that a self driving car doesn't need to read signs, if it can get that data from a formatted online source. (Eg street names on signs, vs from GPS and maps)
