There is a local tradition in Switzerland, and some parts of eastern France and southern Germany where roads are given to cyclists for a "slow up". Cars are banned on the route. Tens of thousands of people are on the road, there are local festivities, music, food stands and drinks and it's a really good time for everybody.
Montreal had one the other day. I think 20,000 cyclists showed up!
The idea that "nobody rides bikes" by NIMBYs shows how blind they are to the reality that a hell of a lot do, and even more would if it were safer to.
