Imagine this scenario;
You're driving along on Youree Drive, then all of a sudden, you notice a police car on your tail. Immideately you get nervous, not knowing what you've done wrong. Maybe he just needs to get by. So you get over into the right lane. So does he. Oh no, you're screwed. Lights come on and you know you're being pulled over.
Horrible feeling, I know. Now stay with me.
