Everyone I know carries a cellphone. They track you everywhere you go, even when the gps is off. Ever wonder how Google provides its live traffic info? New cars have gps and cell radios. If they don&#x27;t already report vehicle position I&#x27;m sure they will in a few years. It&#x27;s probably already used by the three letter agencies. License plate scanning cameras are a commodity now.<p>Google, AT&amp;T, Ford, and the NSA already know where you are at all times. What&#x27;s one more?<p>Sure you could leave the cell phone at home and drive a 20 y&#x2F;o car but that will become increasingly difficult and conspicuous. &quot;Why are you driving that? Do you have something to hide?&quot;<p>I don&#x27;t see this trend as stoppable. I think the best we can do is to implement strong laws about how this information is stored and used. And honestly tracking where everyone drives can do a lot of good. It could allow for much more efficient and fair transportation taxes and eliminiate hit-and-runs for example.
