Be warned - Keep an eye on your speedo!
I sang along to a track that I was meant to be improvising along to for an exam - my teacher had suggested singing while driving. When I looked down at the speedo, I was doing 100 mph on the dual carriageway somewhere between Swindon and Cirencester!
I was so carried away with singing my improvisations that I had completely lost track of the speed of the car :shocked:
This is another case of words having different meaning in the U.S. and U.K. I am not going to post a picture, but if you don't get what I mean google "speedo" and click "images".
