E-tracking, coming to a DMV near you | Perspectives | CNET News.com

Declan is concerned about the privacy implications of tracking cars on the road. This is a valid concern, but a little-researched knee-jerk reaction of mine is that efforts such as this may compromise one of our greatest assets: the open network of roadways.

When you think of it, roads are a lot like the Internet. Once you pay for a car and gas (or public transporation) you have subsequent free access to the entire network. This is a good analogy to the Internet, where once you have a computer and pay for net access, you have unbiased access to the network. Sure, there are pay sites, toll roads, speed traps, and carnivores along the way; but the point is that the majority of the network is free (as in beer), and that we all (individuals and corporations alike) benefit from the network.
I think it deserves to stay that way.

Edit

Another opinion in favor of “toll roads.”
