One factor I haven't seen mentioned in this debate ...

Many roads are not layed out on perfectly FLAT terrain, which seems to be
the assumption here.  It doesn't take much much of a hill to eliminate that
carefully calibrated 3% angle and get oncoming lights square in the eyes.
Uncomfortable enough before, but now with these super-bright lights you
almost have to pull over until you can see the road again.  Add to that the
probability, no - the certainty, that relatively few headlight systems will
keep that ideal alignment over time due to lack of maintenance or whatever.
