Which is good reason to facilitate getting them to the front and away. No?
I get your point but that's not really what I'm talking about. My point is that a motorcycle can pull away with traffic, at the same pace so doesn't "NEED" a safe place to get started from.
A Motorcyclist can sit in traffic and pull away without worrying about being hit from behind as they do so..
I'd suggest that encouraging motorbikes to "get to the ASL" will also encourage speeding away from lights, so its best to let them find a landing spot or encourage them to just sit in the traffic.
The issue that motorcyclist have...and i experience this, is that being on a motorbike means that you can filter to cut journey times and avoid all tailbacks, if you are not going to filter, then why would you risk riding a motorbike. Very often this results in a motorcyclist filtering right up to the lights and not being able to "get in" hence the temptation to use the ASL
But this is just lazy riding (which I am guilty of too) and is relying on the presence of an ASL to often save your bacon.
