I do it everyday, Always have done. Even with oncoming cars, most give you the space you need and every now and then you will get an idiot trying to squeeze you. I had a BMW the other day sat on the white line to try and stop me, I just rode around it.
I work on 2 campuses and if I am off to the furthest place of work from me, there is about 5 miles of 40MPH average speed cameras. These are forward facing so just ride between them when they are doing 40. Stuff them up the inside too on occasion. Not saying I'm right, just what I do.
