Yea, but almost none of those things have changed in the last two year - so does nothing to explain the spike in the last two years.
What has changed in the last two years? Police being told not to police, not to pull people over for minor infractions, police departments being defunded or having their budget's cut - or being threatened with being defunded or having their budgets cut. Can't have to both way folks - like it not, the threat of being ticketed, towed or arrested has an effect on many peoples driving habits.
