Or a lot of the newer cars have the indicator built into the headlight & as you are waiting to get out of a junction all you can see as they come down the road is a bright headlight no idea the indicator was even flashing, & dont get me started on fancy LED headlights that dont seem to dip properly!Daft rear light designs on some cars, particularly the Toyota Prius. Annoys me more than it should.
Also the union jack one and those cars that have the turn indicator in the middle of the red circle.
As the advert used to say "Dont Dazzle, dip your headlights"
