I do not like it when motorcyclist's ride around on main beam especially now that headlight bulbs are a lot brighter.
Indeed. They think it makes them safer, but to an oncoming observer the bright light breaks up the riders outline. The human brain calculates the speed on an oncoming objects by the rate at which it's size increases in relation to its background, and breaking up their outline deprives the observers brain of the necessary datum required to make an accurate calculation. Hence Suzuki discovered that's why they were actually more likely to get smacked, not less. From this research came proper low wattage daytime marker lights and dim-dip systems.
Every time I see a motorbike with its normal headlights on, or a cyclists with stupid bright lights, during the daytime I think back on this, and thank my lucky stars that I'm not into knee-jerk safety reactions. If I do something in the name of safety, I do so because there's a reasonable weight of evidence proving it's efficacy. I do not do so based upon lore, 'common sense', or the word of Ill educated strangers in the street. The British Government and the EU would both do well to take the same approach.
