Go to New York City and you’ll see the inconceivable:
Thousands of people riding bikes in the thickest of traffic, without helmets. In the Land Of The Free, they have the right to bare heads.
But then, you can see the same thing in Paris, London, Dublin, Barcelona, Tel Aviv ... I could go on. All those cities have successful bike-share programs.
Their common denominator:
They waived or rescinded laws requiring helmets for cyclists — at least, for adult cyclists. (Many cities with bike-sharing programs still require children to wear helmets.)
