Nothing, It took them over an hour to charge me after pulling me over. There was a crowd of over 100 people gathered on the sidewalk next to the car and some were yelling at the cops and everyone was filming. IMO they had to get me with something no matter how BS it was to "set an example". It worked because this was all over FB and most blown cars were trailered in to the show instead of being driven after that.
The car was 100% Maryland legal. Mufflers, DOT street tires, seat belts, lights, turn signals, etc.
I even have Maryland Street Rod plates. These plates are only for driving to events, and you have to send pictures of all modifications to the DMV. They have pictures of the scoop and everything on file and told me I'm legal. I'm registered and insured.
