Guess its just as bad in Aus.
My missus is a criminal defence solicitor and sometimes gets in involved with road traffic work. The 'rozzers' told her that they have introduced a new system in the UK (under trial in certain areas - Blackburn being one) that reads every number plates passing by and instantly gives a head-up display stating whether the car is taxed or stolen amongst a number of other useful info relating to the owner. Its led to a massive number of convictions for having no tax, licence, insurance, MOT, driving whilst banned etc.. which has the courts completely bogged down. If they introduce it UK wide it will have a big impact. Personally I think its great because last thing I need is some twat running into my car without insurance!!! I would need to take a civil action which its never worth the time and money for.
