FTFY - As I stated earlier the issue is mostly
people who think their personal benefit is worth the (pretty slim) risk of getting a fine. That applies to almost everything nowadays, from not following the law while cycling or driving (especially parking wherever it suits, ignoring sidewalks, cycle paths, emergency access and whatnot) to littering or the bigger things like diverting money offshore.
I think the problem is mainly "group X of people do something wrong so group Y is entitled to do something else wrong", but I don't know how to break this cycle.
