If the problem is that the urban environment is too well lit, how can the solution be for car drivers to use more illumination? All you achieve by trying to stand out against the background is to push everyone else into upgrading their lights to match - so we're back where we were but with a brighter background. More lights, more visual pollution, more energy used, more weight, and less chance of spotting any hazard that isn't delimited by 50W xenon lights - like, a fallen tree, or a pedestrian, or an RTA.
