I used to get pissed off when sitting in traffic with the engine idling needlessly. It was like burning money to me. Where I live, there are multiple road construction projects going on that will last for several years, traffic nightmares for the foreseeable future! The hybrid actually reduces my stress level.
I can concur with everybody since I sit in traffic on my monster commute everyday, but I have to say it does feel great when everything is quiet and not running the gas engine needlessly in stop and go traffic.
