As a cyclist who routinely rides more than 3K a year, I question the necessity of year-round bike lanes in a city that is below freezing for almost four to five months of said year. Most of Toronto's bike lanes are virtually abandoned in the winter, when ironically, most of those same cyclists are driving along those same routes. 
Why can't we utilize a network of SEASONAL bike lanes that operate from March to November? Then those lanes can be opened up to car traffic in the winter making everybody happy. In Toronto's case, the good of the one outweighs the good of the many.
