Car speed in the zone.. that graph is really telling, showing that in NYC cars never really travel faster than even the slowest bicyclist, and slower than a modest runner. That alone tells you this is the right path. All that infrastructure and work for cars to not actually allow anyone to travel fast. 9mph is very very slow even for the weakest/most timid cyclist.
I support this policy and was a bike commuter for several years, but just to play devil's advocate: Speed is not the only reason people prefer a car over walking and biking. * Some people have mobility issues and can't bike or walk but can drive. * Cars give you environment isolation when it's freezing, sweltering, or pouring rain. * Cars isolate you from other people, which can be important especially for groups tha…
These points always appear in reaction to urbanist policy and all of a sudden care about the minority transit user.
The problem is that the assigned proportion of road space is unfairly weighted to cars and is impossible to shift because people often say things like “cars make it easier to shift things around” and “some people have mobility issues”. Yes, this is true. What is also true is that people with mobility issues can more likely ride (cheaply) modified bikes than drive motor vehicles and people regularly haul heavy loads on cargo bikes (couches, refrigerators) in places where bike infrastructure makes it safe to do so.
If you care about speed in a densely populated city, you’d bike or walk. Flip it around; comfort isn’t the only reason why people prefer to use a car over walking or cycling. You said it yourself already, it’s because you can literally get hit by a car all because drivers won’t give up 1 lane out 4 for a segregated bike path that would stop you getting hit by a car.
