Wife and I moved to the North End last year and sold our cars for that reason. Can't pay Boston rent and also pay an extra $500 a month for a parking spot. I can scooter to work and my wife has a five minute walk to MGH. Coming from California, I thought we would be miserable without a car. Fortunately Boston is really easy to get around without a car. Bike lanes are actually pretty good here (not perfect), and public transit gets you most places easily. There's been a lot of gripes about long waits on the T and frequent shutdowns, but it hasn't been completely untenable.
