On my journey to work yesterday I decided to listen to the Grey Album as it got a recommendation here and it was something I have been meaning to get my hands on for a while. It was really really good (especially December 4th which is my new favourite tune).

On the way home from the office I listened to Radio 4 and Five Live.

I took exactly the same route on each trip (130 ish miles each way), but on the way there I averaged 44.6 MPG and on the way home I averaged 59.9 MPG. It looks like the choice of listening material greatly affects my driving style, I think further investigation is needed!
