Well the train network in all of Switzerland is great. If I want to go skiing, I just hop on a train towards any ski resort and arrive within 1-2h. Wanna go hiking? Take the train. Wanna visit the French or Italian part of Switzerland? Take the train. Works very well and covers most out-of-town trips for me and most people I know. In those rare cases when I do need a car, I just get a rental or use car-sharing (for example when leaving Switzerland). Factoring in the train tickets and the rental car, my transport expenses are still significantly less than they would be if I owned a car.
