Interesting how threatened people are by someone else doing the right thing. Perhaps we can't all immediately give up our cars but the more we can do the better. We sold our second car several years ago and have found fewer disadvantages than we expected...we have never actually had to use a taxi despite being prepared to. I bike or walk every day (with a helmet..it is illegal not to here in New Zealand) and don't look too different to the mother...but I am very healthy and almost get sick. Give it a go!
