Queen's Birthday Weekend and at midnight last night in NSW Double-Demerit Points kicked in, and will be in force till Midnight Tuesday. The Government-speak is "we don't want road blitzes to be seen as revenue-raising, so instead of doubling the fines, we've doubled the demerit points". So, do any sorts of penalties for driving offences act as a real deterrent, or do they just modifiy behaviour at the time of the offence? My observation over many years would seem to indicate the latter; I've passed people being booked and been passed by them at illegal speeds only a minute or two later..... So ..... Has the severity of the fine, or the threat of loss of licence points, made you make a permanent change to your driving/riding habits?
