I'd have thought most people understand what ASLs are for, they are pretty bloody obvious, it's just they aren't enforced so it's more a case of people who stop in them not giving a shoot rather than being ignorant of the law.
Lots of people don't give a shoot then.
"While using an ASL, 36% of cyclists experienced encroachment into the ASL reservoir by motorised vehicles. Over all ASL sites, 55% of vehicles encroaching were cars or taxis and 30% were motorcycles. Different types of vehicles encroached the ASL to different degrees: 68% of car drivers that encroached covered less than half the reservoir while 64% of motorcyclists (64%) covered the whole length of the reservoir.
The proportion of vehicles stopping past the stop line at control sites was 26% compared with 13% of vehicles stopping over the second stop line at ASL sites."
