I drive a first-gen Honda Insight that gets stellar mileage, so I don't really save much money riding To save a gallon worth of gas I'd have to ride at least 55 miles I try to ride as much as possible, not so much for savings (though that's a plus) but for the enjoyment of it and impressing this woman I'm madly in luuurve with at work The thing about owning a hybrid is that they don't like to sit for long periods of time due to the batteries losing their balance, so there are days when I have to drive my hybrid so as not to shorten the life of the battery. On some occassions I drive just for that reason with really no main destination. Of course, I try to make the drive useful, but still it's something I'd rather do on a bike.
