I don't drive at all - just use public transportation (bus, train, light rail, taxi if absolutely necessary). But DH has joined me because of the gas prices. A monthly pass for light rail and bus in our city is just over $60 for unlimited use, and DH has a program at work that lets him buy both of our monthly passes using pre-tax money.
We're getting more exercise now, too, because we sometimes walk the mile home from the downtown stop rather than taking the bus to the stop 2 blocks from our house. We also try to take the bus to the library, movie theater, etc. instead of driving. And the downtown stop is right by a nice little grocery store, so DH picks up a bag of groceries there before he comes home to save on driving to the grocery store weekly. Plus two of the big chain grocery stores do home delivery here, and we get codes for free delivery every month or so. Whenever we get a code, I use that to stock up on non-perishables, cleaning supplies, pet food, etc. - more saving on gas!
We certainly have put a stop to our weekend driving excursions and are looking for more local stuff to do instead.
