This is legislated in the US. Just not enforced and cars became taller since the law was written (-3ft/75ft iirc, may vary by state).
In Scandinavia they actually care about this and high beam use is part of diver training. It's nice. Also semi trucks will happily blind you with a thousand Suns if you forget. So it's rare to get blinded in night driving.
You can get into tighter spaces and it's safer when leaving the spot for pedestrians as the driver has better visibility. At last they did before side airbags.
