Been driving about 20 years in the US, owned eight or nine cars (mostly small to mid-sized sedans and minivans) over the years between me & the wife, and I can't recall ever seeing headlight level controls.
Cockpit adjustable lights have been required by law in Europe for about 20 years. When Xenon lamps arrived, auto-leveling was added as a requirement for them.
