Also, I don't think this has been said yet: but going carless - learn how to do your own repairs. Nothing sucks like having your bike be out of commission for a few days while it is in the shop.
Precisely why a single speed or fixed gear would be ideal. Less things to break keeping the OP on the road. Simplicity can be a wonderful thing. We are often blinded by the next best and greatest thing. Sometimes simplicity is the best thing. If I was going carless, I would either do some sort of public transportation for groceries. Taxi or bus or whatever was available.
Can I ask what this constant insistence that fenders are mandatory? They are not mandatory. A bike can be ridden as a commuter without them.
