My car is to low, my headlights are not legal, no windshield wipers, my engine is not legal, the front window screen is not legal, and I could go on, but, when I get pulled over by the police, which is rare, they have never checked my tires for legal papers??? They always want to know how fast is it? Can we see the engine? How much is it worth? Now I don't argue, I produce my registration and drivers license and I smile.
Cop's are car guys to, don't get overly paranoid.
