Your In-Car Navigation System Is Already Watching You

Oregon recently launched pay-per-mile driving, and it's only a matter of time before others follow suit. Florida and Massachusetts have discussed the idea, and Rep. Earl Blumenauer recently proposed something similar to Congress. Still, at every level and every stage, there's a common objection to the idea of government tracking personal mileage: people find it too invasive.

Now, government surveillance is an especially touchy topic at the moment, and for good reason. But whether they realize or not, many people are already using navigation devices that watch what they do on the road. And unlike what the government would (or at least, should) do with location data in a mileage-fee system, many of the companies that run these devices share that information with third-party vendors.
