I grew up around a transmission shop, so I learned a lot about cars growing up. Instead of being a "stick it in D and go" person, I actually knew what was going on and what led to better or worse mileage. In high school, I decided to get a Pontiac Fiero instead of the common gearhead cars of the time. Since then, I've been consistently beating the EPA estimates in every car I owned. My current cars are a 13 Chevy Volt, 17 VW Jetta and 05 Acura MDX. I also have an 05 Chevy Trailblazer that is sitting in the backyard with some major leaks I haven't had a chance to get fixed up. The Volt is my newest addition, and I've managed to get 46 MPG at 80 on trips by playing with the modes and planning for terrain, but I know this car has a lot more potential in it. Not burning any gas around town is definitely a great thing.
