I found this very entertaining. However he also forgot to include anticipated delays from speeding tickets. I'm sure there are other things that should have been factored in as well, such as sometimes increased waits at lights because you arrived earlier at it, so 25 or 65 would make no difference in how long it takes to get to the ither side of the light.

The big one is stress from the hustle and bustle in the outside lane. I tend to drive at 65mph on our motorways which is 5mph less than the limit. Fast enough to not get stuck between the trucks but you don't spend the whole journey trying to squeeze past people who are doing the same as you.
