Its ronseal, when social engineering is devoid of care & forsight & lacking examples, work reward, the poor uneducated in abject poverty do stuff, like rob bikes inc insurance premiums & lock sells, ect ect aka chaos, personal responsibility is only a small part of crime & punishment, this doesnt make happy for those who get there bikes nicked, extent now that theifs get vans & saw beyond pricy locks & rob dumbphones, the blame is largely with our failed democracy, so much so that commuters reluctant to travel on nice bikes over distance if locked in sheds, then introduce compulsory helmets & cancer vacines.
