Last time I looked up the claims that autos have better fuel economy, all I saw were manufacturer ratings being quoted. I'd love to see a real-world study of real drivers.

I know that personally I can tell I'm a much worse driver in an auto. I'm lazy - so in a manual that means paying extra attention to lights and the traffic so I can engine brake and coast more and avoid stopping and starting from first. In an auto I'm simply lazy period so I end up driving more stop-and-go. I wonder how much of an outlier I am.
