Oregon is running a voluntary per mile travel tax instead of the current per gallon standard. The volunteers do not have to pay the gas tax while participating in the study.
Does anyone really believe the gas tax will go away if the per mile tax is enacted? Does any tax ever go away once it is put in place? So if this goes through we may as well expect both.
What a great way to control travel, especially for the poor. This idea is a greater threat to personal liberty than the Patriot Act. It is much easier to control a non-moving populace.
