Well, I've been wondering about this a lot when I'm out driving - what other people are doing and if they are changing their habits. Yes, this has affected how I drive. For example, we have not driven out to the beach for a very long time as that is a two-hour drive. I also try to combine errands and shop at stores closer to the house, whereas in the past I didn't give it much thought. Maybe more than anything else it just gives me something to worry about, without really forcing any lifestyle changes, you know?!
