Life is a highway

Ok, go with me on this one. Life actually is a highway.
You drive down it, and eventually, you need to pee.
You see a sign on the highway that says you can pee here.
You get off the highway for a bit, and pull into that gas station.
Inside, you find a gross bathroom (thanking God you only needed to pee!).
You try not to touch ANYTHING not attached to you.
As a surprize, the Gatorade in the fridge outside is nice and cold.
You get back to the truck, now relieved in multiple ways.
You pull out a camera back at the truck and snap a quick one of the pumps.
You open up that Gatorade, turn on the CD player and bop down the highway.
Life is a highway, I wanna drive it all night long.
