Emilia, with motorcycles and scooters, yes it's almost required for them to be on the ASL, (especially on that popular junction on Clerkenwell Road/Gray's Inn Road).
As for 4+ wheels vehicles, it's more of a hit or miss, since sometime they don't go on ASL, sometime they do, having said that if you end up thinking about how many cars drive on the ASL, you'll notice cars on the ASL more often, not realising the other number of cars not on the ASL.
I'm not really bothered by it anymore, cyclists manage to get by without the ASL, if a car blocked it, it's not the end of the world, it just mean you'll need to move forward a bit more (it's not a valid reason for RLJ, unless there's an HGV behind you whom they couldn't see from above and the only way to get out of the way is to move forward).
