Once. Convinced the cop that I was indeed just heading home and wasn't out raising hell on a Saturday afternoon. Turns out I knew him from a previous neighborhood incident that he helped several families with (including mine), and he was a gearhead to boot! We jawed for 10 minutes about his BMW track car. All these people were driving slowly by thinking "The dude in the red Cobra got nailed!", and we were just shooting the bull on race cars.
He told me to take it easy and I idled her home with a big sigh of relief.
Had a few other close calls, but that was the only pull-over (knocking on wood).
