Was the car behind you flashing their brights?

It was probably me. Why? Because you were driving 10 miles an hour below the speed limit in the EXPRESS lane!!! It's called an Express lane for a reason, you complete retard - people are trying to move EXPRESSLY from one place to another! If you want to drive at 55 in a 65, or 45 in the 55 work zone (admit it, you did it!), then do it on THE RIGHT SIDE OF THE FREEWAY! Everyone over there is driving slowly, that's why there are so many lanes, duh! You wanna play with the big boys on the left side of the freeway, then it's five miles an hour over speed limit, or nada!
