When he looks into the regulations, it is actually not necessary
The SAE is not very good at its job. NHTSA, yes, SAE borderline useless. They're not interested in safety standards, they're not interested in ergonomic standards, they don't consider human factors, etc etc. And when they do, car manufacturers simply ignore it to pinch pennies. There are SO many things wrong with American automotive regulations and engineering and design practices it is embarrassing.
The way the new Chevy Colorado buries its headlight controls deep within the infotainment system is actually one of the most clever solutions to an extreme problem that I've heard in a long time. Ever since some idiot college-educated engineer decided to combine always-lit gauge clusters with DRLs as bright as headlights, the number of mindless drivers turning their
automatic headlights off has skyrocketed. So Chevy says, screw these dumb people, we'll just default the vehicle to automatic and then bury the headlight controls so deep that only a mechanic will be able to find it. Genius.
I personally think they should tie all interior lighting to the headlights which is how it worked for like 110 years before the late 2000s. That way, at night time, you get in your car and are forced to turn on the lights because the interior is pitch black and you can't even see the shift knob to put it in D.
