Basically, what it does boil down to is that if 85% of the people are violating a law, perhaps it is worthwhile to revisit why the law was passed in the first place, and perhaps decide whether the law needs to remain in place (see: California’s 85th Percentile Speed Law - one of the ONLY common-sense laws to come out of CA).
National sovereignty is another matter entirely.
