I am car-free, for a brief amount of time, when I was trying to learn to drive (had a boyfriend that was pressuring me to learn) I had a Chevette that mostly sat, parked. Eventually, I sold it to someone who needed a simple car to go to medieval events, he was very happy to purchase the Chevette. I used the $ to travel to Brasil. That was back in 2003. I never did learn to drive, I failed the road test, never tried again. I'm 35 years old and female.
I either ride my bike or take public transit. My mother and I live together, she has a car but she works afternoon shift, I go to college during the day. I actually HATE going in the car with her, she drives all over the place and I sit there thinking of the time I'm wasting in her car, I could be doing something enjoyable!
Rarely, my boyfriend who lives right downtown, will rent a car for a couple of hours, this I enjoy, we go to Costco/M&Ms meat shop/other stuff so it's practical, I can get big heavy stuff (10 kg of flour) home.
Other than that, I'm 100% car-free. I take public transit, my bike or I walk.
