Ive only gotten through the first 2 videos. Video 1 was meh for me, I dont think share bike/car lanes are a good use of space in any city that gets significant snow. Since in most cases its not practical to use bikes all the time peak road usage will still occur during bad weather. Also IMO dedicated bike only paths and arterials are a good idea IMO because its safer for both biker and driver and the paths are like a park for all the local residents.
Video 2 is interesting but for small people to become developers they need support from local government. Otherwise shit like this happens and drives up rent/costs for everyone.
If you go to their website https://leanurbanism.org/videos/ its clear that the speaker has very sympathetic regulators. He talks about successfully bending/interpreting rules and not totally getting F-ed over by the the regulators. For example the city let him call access roads parking lots to avoid setback regulations.
Haven't watched the rest
