I drive a car. You [probably] drive an automobile as well. Most Americans drive at least one type of motor vehicle – for whatever reason. It’s next to impossible to live without some form of independent transportation in our country – not completely impossible, but largely inconvenient (truth).

While I’m quite happy with the comfort of my Acura RL, it’s a gas guzzler. Even though I largely work from home, it still hurts every time I hit the pump for $50 per fill-up. My dad was lamenting the fact that Iowa reached $2.70 a gallon just the other day, which would have been “cheap” compared to gas prices in my area.

So, what happens when gas reaches $4 a gallon?

More importantly, at what dollar amount do you truly change your own driving habits? Is that number closer to $5.00 per gallon – or have you already made serious driving schedule recalibrations?
