SteveP sell your car and buy a motorcycle. Depending on your route you could get a motor scooter that gets 100 mpg or if you need to travel on interstate highways get a 250-650cc motorcycle. The Buell Blast is a 500cc bike that gets 50-70 mpg. They vibrate a lot though. Used ones are available for around $2500.00.
I had a 250cc motor scooter that got 63 mpg and had a top speed of 79 mph.
I bought a new sub compact car last July and it only has 1650 miles on it. I'm considering selling it and getting another motorcycle. If I do it my insurance costs will drop several hundred dollars and I'll put ten thousand dollars in the bank. It's tempting.
If you switch to a motorcycle you will be helping the environment. You will use less fuel than a car and you will not take up much space when you park it. You will be able to spend the same amount of time with your family (maybe more since motorcycles are more nimble than cars).
Seriously think about it as something you can do to save money until you can implement your ideal solution.
