It costs a lot of money to own and operate a car. AAA pegs it at about 7 grand per year (.pdf). That's close to $600 per month. Living in a place where you can reduce the number of cars per household provides significant savings. Minor changes to development patterns which would open up that up as an affordable possibility for more people would be a good thing.
Many people see owning a car as an inevitable expense. It isn't.
