I also think there is an element of many people not caring about, or having any pride in their driving, or not particularly caring.
Even when there is no ASL it's rare to see a car stopped on the stop line (same for give-way lines).
People typically either:
- stick the nose of their car a metre or more over the line (rubbish/uninterested/uncaring driver).
- stop half a car length before the line (I'm convinced these poeple think they're on the line but they don't know where the front of their car is*)
*I'm sure this is a wide spread problem - you see it all the time. E.g. people slow speed manoevering when parking or leaving their car a useless half car space from the end of the double yellow (major pet hate of mine).
