Even with a baby I find most of the time we can get by without a car in Vancouver. We're pretty well served by public transit. I can leave the front door and within a couple of minutes be at a bus stop which can whisk me off to another part of the city. Okay, "whisk" sounds a little too glamorous - most of the time you are usually hanging around at a bus stop for a while, before being loaded into a packed bus and deposited at another bus stop to connect to another bus that will get you close to where you want to go. If you're lucky you might get a seat on one of those buses. But, for us, it's fine for short trips.
