Well with led sidelight bulbs and headlights with half moon leds in them on permanently on a straight clear road in broad daylight white van t boned me today. Quote I didn't see you and your brakes are really good compared to mine.
Frankly I am sure dlrs help but they are out there
If they can't see a bright yellow car (and one or two haven't) then DRLs, dipped headlights etc. will not help.
Philip (sospan) posted a link to some research (by RAF?) regarding observation and brain filling in what is seen, particularly with rapid head movement, which I suspect may be contributory to your RTC John. Not only that, but screen pillars are so much thicker nowadays, that it is essential to move one's eye view in order to see around such obstacles. Frustrating, but what is taught now is "make progress" which reduces time at junctions, and ensuring the road one is about to join is definitely clear...
