I have a proper motorcycle and 1962 Vespa, I commute on the motorbike because they are so wanky only a loser would want to steal it and be seen on one. The Vespa is for getting dressed up and good times. I use both in ASL's with never an issue from cyclists, but mostly (90%+ of the time) I stop further forward......because of cars in them. I don't make a big deal of things unless I am on my cycle, then I like to get to ride to the front, point at the (car covered) box, paddle backwards to the bumper and take my time at green.
