Brittney is driving down the highway, trying hard to focus on the very busy traffic, when her cellphone rings.

It's her boyfriend. "What is it?" she asks, "I'm really kind of distracted right now, and we should probably talk later!"

"I was worried about you," he replies. "I know you drive to work at this time, and I just saw on the TV that some idiot is driving their car the wrong direction on the highway, and I figured I'd better warn you..."

"It's not just one car that's going the wrong way," she answers breathlessly, "There's hundreds of them!"
