We all know that the law of car-driving-assholes means that any bike lane that a car is capable of entering, will be entered by a car = risk of death/injury. The only way for bike lanes to be a safe method is to introduce barriers so cars CAN NOT ENTER AT ALL. Sadly there are so many roads that are too narrow for these bike lanes to exist as well as allow two way traffic as well as parking that I think the only way is to create one way roads from the old 2 way roads and have a segregated bike lane use up one car space, with barriers to cars, and parking one one side only. They have created trial bike lane on bloor street in Toronto, with only one parking lane (which alternates from side to side.) Bloor still has 2 way car traffic.

I think one way is the way. Then with self driving cars(cab like, but lots cheaper) reducing the numbers of cars will help. http://www1.toronto.ca/wps/portal/contentonly?vgnextoid=18cc...
