Dave: What's with all the traffic?
Jessica: there's a stalled vehicle in the middle lane up there
Dave: Oh. Did you see it?
Jessica: No. The electronic traffic informational sign told me.
Dave. Oh. I never read those. It could say there is a giant fire ball in the middle lane. It could say there is a car-eating dinosaur up ahead and I would still be all "weird, what's up with the traffic?"
