When a group of drivers all going the same speed down the highway manage to block the entire road so that nobody can pass. It's not a traffic jam because everybody is still moving.
I was doing 75 down the I-10 and expected to get to Phoenix a little bit earlier than expected when I hit a road clot doing 70 mph. It wouldn't break up and allow me to pass and I became part of it.
