I think one of the reasons I enjoy this show so much is that it is very easy to watch! This are simple people with relatively simple lives who have joined up to travel together to beat the system - and really that is what the carpool lane is - beating the system of traffic jams. Of course when you peal away the layers they aren't simple at all; they all have their own quirks and fears. The humourous dialogue is brilliant! I was hooked really after the first episode, but as the weeks have gone on, it has just got better and better - which is how it should be for a new show! This and Pushing Daisies are the winners for the season!
