It's not impossibleto survive without a car.
It's not impossibleto find a life partner without a car.
And as long as you're happy living without a car, that's great.
However, you may discover that life throws you a curve somewhere along the way, and all of a sudden you may discover that owning a car is the better option.
You're still in high school (right?) ... so just barely beginning on life's journey. Some people's lives follow the exact plan they have in mind, but for some people everything changes and you find yourself in a place you would never have imagined.
When I was 18, going to high school in a small country town in Canada, I never imagined all the twists and turns my life has taken, and especially that I'd be living in Australia later in life, halfway around the world. I've gone through years when I have lived car free ... I've gone through years when I have lived car light ... and I've gone through years where the best option was to drive a lot. Careful consideration went into those options, weighing up the pros and cons, costs and benefits, and I made the decisions about what would be best for me at the time.
