Instead of cracking down on a handful of people racing cars, why not crack down on suicidal levels of waste resulting in irreversible debt and taxation?Thing is, if they had cracked down on the violators HARD from the beginning, some of this wouldn't be necessary. Why didn't they block sales of these devices? Or at least restrict them for specific uses, like off road only. Log the VIN and marry it to device sales so that those vehicles could not get plates or on road insurance. If one is caught on road, impound it and forfeit it for auction or destruction.
Some states are harder on violators than others. Some will take a safety violation off the road until repaired, some will cite and allow X days to repair, others don't even have safety or emissions inspections at all.
