Got to be honest, that when I see a personalised number plate, the only word I really think about is the word "TWAT".
Nothing to do with them being 'expensive wastes of money'. Its just that they are well.... just dumb!
I suppose I see it almost as a form of personal advertising about yourself, to give a certain impression to the world. And if you feel the need to do that with your brand of car or what number plate your car has, I think it doesn't say a lot about you. Especially if it suggests you aren't very good at spelling your own name!
When it comes down to the money argument I think, if you want to drive a nice car which might happen to be worth a lot of money, because its a great car, fair play to you.
If you want to drive a certain car because it says something about your status, then you are a twat. Doesn't matter what it is; whether it be the pimped up car with blue underlighting or the chelsea tractor or the Audi Rep Mobile... Drive it cos you like it, not cos its going to impress your mates, the girls, the business associate, the playground mafia. (Delete as applicable).
And the number plate thing really does fit in with this image to the world business rather than just getting on with your life without making a fuss about it to everyone else. Its all about the shoving it down someone else's throat saying "HEY LOOK AT ME!" type attention seeking.
But then I think its cos I'm getting old, and I really don't get 90% of whats on social media (particularly twitter) and how everyone has to advertise the size of their latest turd, complete with photographs to compete with everyone else's log pictures.
No one seems comfortable in their own skin and confident enough in their life to just enjoy it without this need to compete with the world and his wife.
So yeah, thats why I hate personalised number plates. Its all the need to better others in someway.
