Hmmm. I don't think much of the idea myself. I don't think it'll do anything to make our presence on the road more respected (and some of the comments bear me out on that) and it may well lead to increased calls from motorists to confine us to cycle lanes at all times, whether we want to be there or not. Plus, I occasionally end up with my tractor unit in an ASL at traffic lights, simply because it sometimes takes a while to stop - cameras are famous for their lack of discretion and I'll be very displeased if I start getting fined every time that happens. Finally, there's no harm in putting one's nearside wheels into the cycle lane (as long as it's clear) to pass, say, right - turning traffic.
