I'd like to see headlights banned in built up areas. They are not needed for vision and they create too much glare, masking anything to the side of the vehicle and making it difficult to judge approach speed.
No, no, no! A million times, NO! Sorry to disagree but that is one of my (many) pet hates with regards to my fellow road users.
Sidelights in a built up area just blend into all the other lights such as street lights, shop windows etc.. In wet conditions they are all but impossible to see in your mirrors. They may not be necessary for vision, but they are most certainly needed to BE SEEN, which IMHO is more important.
As a motorcyclist with a plastic visor to see out of, with no windscreen wiper to clear it, a car with sidelights on becomes invisible in the rain.
As an HGV driver, I NEED to be able to see a car when it is a long way back, as my trailer alone is 45 feet long. A bit of rain on my mirrors, and I can assure you it is VERY difficult to pick out a car with sidelights on. DIPPED HEADLIGHTS only please!
