I have two little kids. I also own an electric cargo bike. It has replaced over 2,000 car miles in the past year. I can bike to the grocery store, with two kids, and come back with a week's worth of groceries.
You're making my point for me. I'm not saying bikes don't work. I'm just saying that there are many times that they don't work. And it sounds like you're a bike lover and even then, you couldn't replace 8k-13k a year of car travel.
And I'll note that you're using an electric bike. That's like an electric car, but with only two wheels. So you're really on the wrong side according to this article.
The average mileage in the UK is 7k miles annually. Americans just drive too much.
Okay, some hipster with two young kids can take a saturday jaunt on a super-long, super-expensive electric bike, but that's not going to work for most people when it's cold, dark and rainy.
