Not really a car joke - more a blonde joke really but still brings a smile...
Blonde whizzing along in her little red sports car with the top down doing way over the limit.
She gets stopped by a female cop - also, as it happens, blonde.
"Drivers licence please" says the cop, whereupon our blonde rummages around in her bag. "What does it look like?" she asks. "Well it's rectangular and has your picture on it" replies the cop.
Finding her vanity mirror and looking at it and seeing herself, she decides that must be it and passes it to the cop. Looking at it, the cop says "OK, you're free to go. But why on earth didn't you tell me you were a cop?"!
