I'm glad to see that many teenagers and young adults today are looking into going car free.
When I was a teen (back in the '90s) I also went car free. I never bothered to get my licence at 16 which was rare (and a frequent source of ribbing from my buddies). The fact my parents were adamant that they weren't going to pay for my licence and car was a big factor. I couldn't afford car ownership back then. I rode the bike all summer and took the bus all winter. I biked to school. Then I biked to my summer & part-time jobs. Next thing you know I'm done college and I'm bike commuting to my full time job from spring to fall. Even though my dad taught me how to drive around the cottage back then it took a while before I got around to getting my licence. Now I bike commute year round and I rarely drive the family car. My wife does 99% of the driving.
