This is awesome news I hope more companies pick up this idea and run with it. I would certainly get my hybrid right now with that extra incentive!
Would you drive a more fuel efficient vehicle if the company you work for paid you thousands to do it? Hyperion Solutions offered employees $5000 to buy a car with an EPA rating of 45mpg or higher. Google offers $1,500 if you buy a hybrid, $2500 if you lease one.
