I changed my habits about 4 years ago. Drove an old Mustang. It's not fun waiting for a heat soaked starter, or a carb needle going haywire causing my engine to flood, or smelling like old car everywhere I go. Now it's a weekend car, and my daily beater is a fuel efficient Focus. No habits required. I love driving, but I hate running errands. I have been combining errands since I started driving.
On a side note this happened the other day.
We went to see a movie with a big group of friends. A few tried to use the student discount, and the theater said they only except them on Thursdays. Why did they start doing that? Gas prices they said.
In terms of lameness, that is the ultimate WTF in the "because of gas prices" card I have seen played.
