It scares me too. What happens when this car is 15 years old and the third owner is to broke to fix things when they go wrong? Will they be driving blind, or blinding everybody else?
You are someone who hasn't lived in many of the 50 US states, apparently: there are no state car inspections in most places. Ever. I know it seems amazing to those of us who are accustomed to them.
Actually, you would probably not get away with having failed auto-headlight-dimming because you would annoy a cop going the other way and get a ticket. But features that aren't so obvious will go uninspected in many locations.
