Not so strange, impossible or impractical - most journeys we make are short, and the main reason we reach for our car keys is more down to habit and in the UK, because if you ride, you risk someone trying to kill you and them blaming you because they didn't see you.
Living in a land where the infrastructure allows most journeys to be performed by bike and seeing that, surprise, surprise, that's what people do shows it's not just a child's unrealistic dream.
All over the developing world, the bike is already the preferred work horse, but in China and India, the emerging middle classes are being herded into cars by advertising and promises of a life that the west seems to be enjoying. They can add the heart and respiratory disease and road deaths to their new found riches. Or they could take the emerging trends in from the Netherlands and Denmark and think about where all these people are going to park their new cars (electric or otherwise) and instead provide them with the integrated transportation so that the car, a useful tool when used in context could be available when you need it. It's only down to the might of advertising that everyone needs there own to feel normal -it can be normal to share, hire or borrow one and not need to have several sitting cluttering up the streets.
