As discussed many times past, including on HN, if you live in or near a major city, and in a country or area which prioritises goood public transport, you can get by admirably --even better-- without a car.
As soon as you move even a little away from the metropolis, and/or to somewhere that doesn't prioritise good public transport, access (at least) to a car becomes close to a necessity for many activities. This rule holds true in my direct experience in the UK, US, Switzerland, and Germany.
For example, in the US compare living in Denver to a small town a couple of hours' drive out in the sticks. Or in the UK, living in one of the major cities to virtually anywhere in the countryside.
