Sure, you can ride a bike. Now, tell me how you would transport groceries for a family of 4, or how you transport the kids to doctor's appointments, for instance. What about people who physically can't ride a bike? What if I'm coming from 15 miles away?
Surely as someone from the area you've seen the countless folks with cargo bikes transporting their kids? I live 1.5 mi. away from my grocery and I take panniers and shop for a family of 2 (though I understand that kids need a lot more things than adults do, so this isn't an apples-to-apples comparison). And if you're coming from 15 mi. away, you're a guest, not a resident, so either take transit and a bike share or circle the block for parking. I don't demand a house in your yard, and neither should you demand a parking spot in mine. Also, what about the folks that physically can't drive a car but can ride a bike, or the folks with poor reflexes or vision that should not be allowed to drive and yet are given a pass in the US because it's so driving centric?
