Why? Why should anyone care how much someone makes use of something they worked for and paid for? The day that happens I might as well move to china.

I don't think one needs to be a communist to believe it to be immoral to consume a larger than necessary proportion of a scarce resource.

And if philanthropy isn't your bag, how about selfishness? Would you rather guzzle gas for the next twenty years of your life and then walk, or sip gas for the next forty?

Edit: 20 and 40 are made-up figures, of course, but the principle still applies whether it's longer or shorter.
