Interesting view, Terry. I guess the cars turning across bus lanes aren't expecting bicycles to be coming along? Surely they will be, and if they are, then they see any motorcycles that come along.
Surely you are far more in danger in the middle of the road than in bus lanes - the danger of being hit by a car that's turning right or, more to the point, pulling a U-turn, or even just swerving to avoid something like a bus, are astronomical. And there's the added danger of being pushed into the path of oncoming vehicles!
I fail to see how anyone can think riding in a bus lane is remotely as dangerous as riding in the middle of the road. How many car drivers use their mirrors when turning right, or check their blind spot? Not many. I know that from bitter experience of my own, and from seeing several fatal accidents.
