A vespa or scooter is a pretty good way of getting around too. I had one when I lived there, and it was much more convenient than the car - easy parking (although sometimes the dickhead meter maids would give me tickets for parking the thing on wide sidewalks between trees...hrumph). If it's rainy, you can dress up a bit more than is comfortable on a bicycle. The drawback is that you're still pretty much stuck in the city, as you don't want to/can't take scooters on freeways.
