Interestingly, this video isn't really about physical barriers to biking. It's about geopolitical barriers, economic barriers and cultural barriers. The speaker is coming from a strong analysis of society, invoking race and class to help explain how the option of biking as recreation and transportation don't enter into the minds of people of color, and it feels like calling the video "Physical barriers to biking" diminishes that analysis. A video with this title might be about infrastructure. Physical stuffs. This video is about much more.
I didn't meant to put physical in the title. I was trying to do too much while getting the video posted. Thanks for bringing to my attention
