Gas isn't much of a necesity if you organize your life. I own a scooter and a bike. I use less than 2 gallons of gas a week. Occasionally I need to carry more stuff than my scooter can handle. I have any number of friends who are happy to accomodate with their cars.

I spend more on liquor, though that is still a minor expense. A few pints every couple weeks and a bottle of single malt every other month or so. Say $250 a year. Gas at current prices: about $170.

Of course, the more gas you use, the sooner you'll be forced to change. I can't wait until that time to here all the whinning.
