I found this on another list and I thought this was good so I thought I would share; from Bruce Rosar:
Those who operate heavy equipment (i.e., most motor vehicles) within the public ways pose an extraordinary danger to the person and property of others. Our government already keeps a watch on such people. If you feel that the government should keep a closer watch, please feel free to advocate for that.
Instead of abandoning our own rights of way to those people who are not worthy of the public's trust to operate heavy vehicles safely, we should push our government to put the privilege of operating such extraordinarily dangerous equipment beyond their reach.
