If you don't use a car, how will you get to places?

There are a few very cultural biased responses in the thread. Your statement seems really ignorant to me. Obviously your usage of alternatives depends on what the situation in your area is like. There are cultures that are very much into bicycles (Netherlands, Denmark), some where just no one even has a car (China, many other non-rich countries). Some where public transport is crappy and car is the only alternative (Fill in your own). Some where many alternatives exist. It is for everyone to find out which alternatives exist in her or his locale. It should be easy to figure out the local transport abilities. On an international forum no one can give all-suitable advice that fits every situation.

For example I choose to move into the inner city of a 400.000ppl city in Germany. There is much public transport (bus, tram, subway, distance trains) available, including a great website that tells me how to get from A to B anytime. As a backup there are taxis. But since I am young, poor and healthy I mostly walk everywhere. If is more than 1,5h walking distance I take public transport.

The OP probably does not suggest to never ever drive, but to make a reasonable effort to stay safe. Reducing driving if possible is one way. If it is not feasible in your area, than you still can do the other things. Since we deal with probability here it is all about comparing alternatives and improving your odds.

From a financial viewpoint one can calculate the total cost of a car broken down on usages, vs. public transport vs. increased rent for a more favorable place. And if you do not need a car on a (work)daily basis you can find the local car-sharing offer (no idea if the US provides it. In Germany it is slowly growing), rent a car at times or take the Taxi.
