Yeah for the record I am just about to turn 22 and I don't agree with any of this "car-free" bull****.
Cars are a necessary form of transportation. If my girlfriend falls down the stairs and needs to go to the hospital with a broken leg, I'm not gonna pay for an ambulance, and I'm definitely not gonna throw her on my handlebars and bike her there.
I bike as much as possible, and walk when with people who don't ride, but at the end of the day, a car is necessary at times. I'm not going to throw the ingredients for a big dinner for my friends into my bag, and I'm not going to carry 4 cases of beer home in my bag on my bike. That's what the car is for.
