This new law is really retarded, it does not address the reasoning for such a law, nor does it increase safety. It does create more lateral motion on the highways and increases the risk of accidents.
At a bare minimum this law should be amended to allow traffic in the left lane when passing ONLY if it is not a divided highway. A four plus lane highway with the potential for head on collisions might be the only reason.
If you apply logic to this new law we will soon be changing all two lane highways to one way so as to not create the hazard of head-ons.
Now is the time to fix a dumb law, the only plus to a law like this is to increase the revenue from traffic fines and take money away from citizens that already are in a bind due to the current economy.
