The result is that in rain or mist or even fog people don't put their lights on as they think they are already "on" and the rear remains unlit. I have seen this countless times in light rain on motorways at high speed. The regs would appear to assume that drivers follow the instruction to turn lights on in times of poor visibility (fat chance!).
Surely the system should be "side" lights as "running" lights at both ends with more at the front as needed?
My limited understanding Duncan is that daytime running lights were developed for the Scandinavian market where they raised awareness of an approaching vehicle on long, gloomy stretches of open road with little traffic. The idea was then rolled out wholesale to other markets without a great deal of thought or analysis. Studies in the U.S. identified zero benefit.
