I’ve been seeing this a lot lately and saw it twice on my way home from work last night, once on an expressway. It seems to always be newish SUVs from US manufacturers. The cars are driving at night with headlights and even fog lights on (with no fog in sight) but no tail lights! They are completely blacked out from the rear which seems really dangerous. I understand that this is just a case of idiot drivers but why would any manufacturer enable this practice by allowing such a light setting for any vehicle? Are they trying to improve gas mileage by eliminating the power drain required to light up the tail lights???
Those are just morons who don’t know how to use their lights. They’re running DRLs because their lights are set to “off” even though cars have had an “auto” setting for the last 20 years.
Also, how would battery powered lights affect the gas mileage?
Not all cars in the last 20 years have auto headlights.
