I'm not totally sold on the DRL studies, but I can see where they add visibility and safety on 2 lane roads (not limited access freeways). I'm glad the H3 DRLs can be turned off via the override switch, but I would prefer the ability to leave them off. Mercedes has a nice solution that allows the dealer to program them on/off and I did have a Toyota Camry rental that had a separate switch position for the DRLs.
So the new H3's will have improved headlight DRLs instead of the orange signal light DRLs. The "parking light" DRLs are borderline illegal in California and other jurisdictions, but hardware laws are rarely enforced here. And mixing the DRLs with turn signal lights is a bad practice and potential safety issue. I hope GM (and Lexus) change all their DRLs to headlights and make them driver selectable.
As far as turning off lights and AC to save gas....Yea and running premium gas for the hope of better mileage on an H3....Good luck.
