More and more lorries and vans are driving around with stickers on the back asking the question:
How am I driving?
They then provide a phone number for you to phone in with the answer.
It always makes me incredibly nervous when I see one of these. You see, I’m not sure I know enough about the workings of the internal combustion engine to be able to provide a comprehensive answer and if they put me on the spot and force me to answer I think I’d just say: “the engine fairies.”

This post was the Chardonnay of my humor day.
I’m not sure if that’s a good thing or a bad thing… but I’ll take it!
