Spies on the road

Spies on the road: Washington State’s using motion data from your phone — yep, the same one in your car’s cupholder — to find speeding hot spots. A Michelin-backed system anonymously logs braking and acceleration, then tips off the State Patrol. The upside? Fewer crashes. The downside? Your commute just joined the surveillance state. Not tracked personally, but just enough to ruin your shortcut.
