Non standard numberplates

What is the story with enforcement of the rules on number plates. It seems to me that about 1 in every 10 cars I see has some sort of non standard plate and it's not just "boyracer" cars either. Many of these plates are far less legible than the standard plates, the swirly font ones are particularly bad. When I see a non standard plate on a car I often think "tosser" and I notice that cars with these plates tend to be driven badly. It is pretty sad IMO to see a brand new car where someone has gone out of their way to fit swirly font plates or some other tacky crap to it. Do people actually think these look cool.

The worst type of plates are the ones which are an Irish reg but on a yellow background. Do these eejits think that people are going to be fooled into thinking its a NI reg. There are an increasing number of these about and from what I see there is a very strong correlation between dangerous driving and having this type of plate.

In GB if you drove around with plates that were obviously non standard you'd last about 5 minutes before being pulled over by the police. The same enforcement will have to happen here before barrier free tolling comes in.
