it struck me today that we could use the rear sunblind as a way of 'communicating' to other road users

so what slogans would you like to 'unveil' to an unsuspecting other road user

"Turn your chuffing fog lights off you muppet!"

"You're inidcators are Fscked Mr BMW driver!"

" Hello Mr Policeman, I know I'm speeding but its worth it to see your face!"
