The thing is... if I was pulled over and checked by a policeman because I look like a dodgy bas**rd in a flash car, I could accept that - that's their job and I'd rather they did spot checks like that.
But to make up something to make you sound like a criminal is just plain stupid... no-one likes to talk to a total jobsworth who doesn't seem to be from this planet!
If the police want to stop and check my car then I think that's all good (after all the Yorkshire ripper was caught by a random traffic stop), but FFS don't make up petty excuses to fine people!
