Hmmm, How many times has a bike pulled out straight in front of you from a side road? Ask any biker and that happens a lot the other way around. The consequences for the biker are always a lot worse. Personally I feel that if all vehicles had their headlights on at all times then nothing would really stand out like bikes do at the moment. As for visibility in the wet , its not a problem. I spray my visor with aircraft windscreen rain repellant. If all else fails, you can always lift the visor unlike a car windscreen.
