- Children love to ride bikes when it is safe to do so, from personal experience. - If you keep some (inverse of most) streets open to a small amount of traffic (Like Barcelona's superblocks [1]), the elderly and those with disabilities are still mobile. - Why is privacy needed when travelling? Do you require a private enclosure around you when you are walking? I've met many interesting people from all walks of life while cycling and on public transport that I wouldn't have had the chance to meet otherwise, just like I meet people when on foot. Car free streets provide many more interesting street restaurants/businesses for such activities you describe. - Travelling with the whole family on a train or cycling is pretty good. For example, in Sydney the seats of most of our trains flip so you can have up to 6 people facing each other. Though I am excited for self driving cars because we won't need so much parking!
