If one can afford a Model S, one can afford a lawyer to ask the judge for the court's accepted definition for "display of speed". My money says a Tesla with pedal mashed and launch control on would not fit the definition. All one is left with is pulling an illegal number of Gs, which I don't think cops have a measuring gun for yet.

In the real world, I've launched plenty hard on motorcycles on a regular basis to this day, and have occasionally blown past a sitting cop while doing it (getting around traffic from a light, or what have you). No smoke from the rear tire, front wheel stayed on the ground, speed not exceeded (or not by much), I've never been pulled over. Squeal tires, or have another car next to you accelerating at the same rate, or maybe even an overly loud exhaust, and now you've got problems.
