Australia, Netherlands, Germany, Austria, etc, have well-enforced traffic laws. Speeding is the exception rather than the rule, unlike the United States, where one can expect the flow of traffic to be 10-20 miles per hour over the posted limit. Yet these societies don't suffer from an excess of enforcement or consequences in other areas. For example, it is legal to walk around in public with a bottle of beer in virtually all of Europe.

What we have seen in the United States is a reduction of many hardly-enforced laws. Jaywalking and minor drug possession have been decriminalized in several US states. This is due to voter interest. It will continue to be up to the public to decide what do to when enforcement can catch up to excessive laws.
