It’s been years since Philadelphia first put in bike lanes to make the streets safer, but it hasn’t always worked.

So why even have bike lanes if they’re not protecting cyclists? On this episode of The Why, PlanPhilly managing editor Ariella Cohen explains how bike lanes came to be, and why cyclists still feel vulnerable while riding in them.
