I used to see this stickers on the back of cars and thought they were advertising their fuel economy. Thought it was the stupidest thing in the world. Then I realized they were promoting the fact that they were in a marathon, which is kind of just as dumb. I mean, every car should be capable of running a marathon.
I'm metric, but I'll take your word for it that the maths works out
Right. Those stickers are a bit ironic when on a vehicle.
