I think you are right about reactions to riding in the rain. It is possible to be to cautions, like trying to cost through a corner with no power to the rear wheel which is the very wrong thing to do. I have caught myself doing this so I try to ride a little slower but with normal procedure. I have also heard it helps to over inflate the rear tire by a pound or two. Ironically the slickest place I have found is a 4way stop a block from my house. I always take off in second from it.
