Roads are getting downright high tech on the west side of the state (no need to be jealous, we don’t have the congestion to warrant this kind of thing). Starting with I-5 next summer, new signs will warn drivers of slow traffic ahead. How will they know traffic is slow? Because sensors embedded in the pavement will send them a message to tell them. Then they’ll rise up and take over the world. Oh sorry, got a little carried away there.
