No doubt the law can use some fine tuning. But lets criticize it for what is not included, what is included is good, just doesn't go far enough.
Well yes, but to generalize based upon forcing compliance by folks who don't have a sense of personal responsibility and leaving that in the hands of the police to adjudicate with individual choice is always going to be a rocky road.
Those of us living in rural communities where it might still be common practice to leave your pick-up with the key in it for the neighbour to use when needed are going to bristle at these types of laws being interpreted to mean locks and chains put on everything from the tractor in the shed to the combine out on the back section, four miles from anyone's eyesight.
As long as the laws are written in such a manner that their spirit or intent is clearly spelled out for sensible law enforcement officers, from cops to judges, to interpret with reasonable consideration
as this law seems to be with the use of words such as "prohibit or discourage" there should be no problem until a cop on an ego-trip reads something into the law that is not actually spelled out, described or defined in it's intent.
I categorically disagree that this law needs further additions.
