That is all true, but even if properly aligned, most new cars in the USA have awful headlights with no sharp cutoff line at the top, so there is no way to point them to light the road well while not blinding oncoming drivers. Moreover, like I mentioned, quite a lot of European cars have systems to automatically align and even steer/shape the beams dynamically, and do not require that type of adjustment. VW's "dynamic light assist" for example, actively detects oncoming vehicles and dynamically reshapes the lighting pattern to block most of the light going directly towards other vehicles, while still lighting everything else.
