Any clown who thinks spending $7500 to convert their hybrid into a plug in in response to high gas prices is an idiot. They are already driving hybrids, which take quite a while to become cost effective themselves. Adding another $7.5K to the price makes them even less cost effective. How long will it take them to save $7.5K in gas to make up the cost? 10 years?
If the tree huggers want to do it in the name of the environment so be it but people who think they will be saving money in the long run are delusional. People do stupid stuff when the hype machine is cranking thats for sure.
