I’m always impressed when I see them cross a double yellow to go around something. How do they know if it’s a temporary stop or not? The other day we were in traffic and it crossed the double yellow to go around a bus as if the bus was parked. Ended up between both ways awkwardly when it saw that it was just traffic and there was nowhere to go.
