At Philz Coffee in Palo Alto, Calif., a kid who looks like he should still be in high school is sitting across from me. He's wearing Google Glass. As I stare into the device's cyborg eye, I'm waiting for its tiny screen to light up.

But they notice you: A scanner can ID thousands of plates a day. And a new ACLU report says the vast majority of police agencies now use them.
