Those cars probably had one or more of the following:

blue-tinted H4 bulbs in nonQH units
RHD H4 units
H4s in US-market lights
lights misadjusted

A proper LHD H4 unit has a low-beam cutoff and, correctly adjusted,
will not glare.

All cars here (apart from some 1984-1990 Japanese-market Toyotas)
have standard H4s. No glare problems, even with 80W low-beams. No way
would I wany glow-worm US lights! I like to SEE where I'm going.
