I don't understand why headlight elevation isn't standardized.

It was. We had sealed beam headlights for a while till we didn’t. There were common rules for aiming and it worked. The lights weren’t all that bright and the styling was not stellar, however.

		I remember having to take my car in to adjust the aiming of the headlights after it didn't pass inspection. So we used to take things like this seriously. I just had my car inspected last month, I don't even remember them hitting the horn. I'm guessing they pretty much just shove a sensor up the exhaust pipe and call it a day while accepting your payment.
