Dutch residental streets are designed narrow to reduce speed, cyclists can cycle here too in safety. We added speed bumps and flower beds make drivers zig-zag to reduce speed.
The best solution to traffic is giving people viable alternatives. All these roads mean nothing if people can not cycle or walk or take public transit, and each person doing so is one less person in a car.
Cars are not "burried at the bottom of the transportation pile". There is no top or bottom, all traffic is important and get's the appropriate attention and infrastructure. Unlike in countries like the USA, it is not "cars vs the rest"
