this is the danger for you and me on the road with the bike. Luckily I never fall because of oil on the road. But when I driven in the big city Frankfurt once, there was a lot of oil drops on the road. My backweel turning and turning... Because of raining same time. But I heard from a friend that the got hurt but such oil drop and slip away. Very bad and dangerous. I never wish that to any Biker.
