Infrared and ultraviolet cab

If you are in this cab, there are monitors that show you any radiation you desire. Passive infrared cameras on the cheap version. And passenger controlled point and focus on the more expensive. An insulation salesman would be thrilled to find thermally leaky homes. Detectives would easily find pot growing garages. Tourists would see the "Hidden City".

It would just be fun to see what your missing, because our eyeballs evolved in green jungle.

Limited appeal, but a couple such cabs in every large city would have plenty of business.

Some military vehicles must already sport something similar to see through fog and smoke.

Fluke and others have hand held viewers for a thousand dollars. An existing cab company could start by renting a viewer and a driver for an afternoon, and see what happens.
