If the back of your car looks anything like this:
You are NOT ALLOWED to go under the speed limit. Ever.
In fact, if you have any numbers at all stuck to your car -- whether it be a sweet Audi or a piece of shit '72 Pontiac -- and these numbers actually belong on the cars of NASCAR drivers living or dead, you are required to go AT LEAST ten miles per hour OVER the speed limit at all times.
To reiterate my point: Even if by some chance a deadly virus killed everyone in the world but the cops and YOU, and their single, all-consuming purpose for living has become repeatedly pulling your sorry ass over, BY GOD YOU WILL DRIVE FASTER THAN THE POSTED LIMIT.
Do you hear me? Good.
Now go home and pull that sticker off your car because you're an embarrassment to NASCAR, and that's a pretty effing hard thing to accomplish.
