I’m with you......notice the odd car every now and than but it doesn’t bother me.
Did have a hire car awhile ago and got flashed twice, so I hopped out and had a look at the front and noticed the fog lights were on, worked out how to turn them off only to be flashed a number of times during the hire.
Figured it must have been an issue with the headlights as I always drive with headlights on.
