When I was a kid, trunk carpooling was useful for getting a bunch of us into a drive-in theatre. Have no idea what sort of Zen state of mind Wally would achieve by himself in the trunk of a car. If it wasn't too cold outside, he might just stay there until he was brought back to work the following day. He would have to have a very large thermos full of coffee, however....
Logically, the "no-stop" lane should be for large, heavy vehicles that waste the most gas when they have to accelerate out of a stop. Illogically, we allow Priuses to have a car pool access sticker when they waste less gas in the stop and go traffic than the big heavy machines do.
Not sure this is material for a Dilbert strip. I'm just sayin'.
@red33410 I doubt Scott colors the comic... probably oversaw the colors originally picked for characters, but doubt he needs to mess with that now.
@Lupo Uhh...cop will still pull you over if you look like only one is in the car, even if someone is in the trunk....no, that will add a bit of time to the journey, and uh, the driver may not look like a moral citizen with a guy crammed in his trunk.
