I was going to post something else this morning but, while I was looking up the reference, I came across the Lightmare campaign.
This is appealing for restrictions to be placed on over-bright headlights. Full beams are fantastic for safely navigating dark country lanes but drivers can dip them when another vehicle approaches. I had thought a lot of drivers were forgetting the courtesy of doing that but apparently some of the current generation of car lights are as bright as full headlights even in dipped mode.
Being able to see clearly is good but the roads do not become safer if you dazzle those in other vehicles. If you must turn day into night to feel that you can drive safely, the way to do it is to wait a few hours for the sun to come up before setting out!
