I didn't read this entire column, just the beginning. It's an opinion piece, and all I wanted to know is that Oregon is looking in to a Vehicle Mileage Tax, where you would be taxed based on the number of miles you drive, as recorded by a GPS unit. There are so many problems with this that it's hard to believe they are even considering it. Hmmm... Lack of privacy, for one. I find it ironic that many of the same people in Oregon that were up in arms about the Patriot Act and requiring ID for voting are in favor of something like this, which so much more invasive. I don't think the government needs to know where I am anytime I use my car. I also think it's an attack on my liberty to charge me everytime I travel. The right to travel freely within our borders is a very valuable one, and this would take away that right. Suddenly you'll only be able to travel if youu are willing to pay for the priviledge. Of course soon enough they'll have a progressive VMT where poor people get paid to drive while rich people have to pay triple the normal rate. Makes sense to me....
