I don't have a car, but the city I live in has an excellent car sharing system. I just checked, if I wanted to go hiking tomorrow, the nearest suitable car that's available all day is 200m from my place. Booking it for 8 hours and driving 100km would cost me 33€ ($41), all costs included. The key is in a lockbox that opens with a card, so it's available 24/7/365 without another human in the loop. Booking is easy and convenient. If the weather were any good tomorrow, I might have done that and gone winter hiking. Not having a car doesn't have to be as limiting as you may think :)
