Of course you should ban cars from areas of the city, but bikes still need to travel between those islands. If your “pedestrian area” is an island everyone has to drive to get to, it will fail.
At that point, you can do things like pedestrian bridges, over/underpasses with roads and streets, or level crossings with signals. Instead of trying to mix traffic everywhere, have the two systems meet at certain well designed controlled spots. Instead of bikers being in a near constant state of “I am in traffic”, have certain points along their journey be “I am crossing a road.” These areas will almost certainly drive both cars and bikes to stop, and then one or the other gets to go at a time, rather than both are in motion failing to predict the other’s movements.
Bikes are a much denser form a transportation; you can have 100s of bikes cross an intersection in the time it takes 4 cars to cross. You don’t want a traffic system where both have to wait, you prioritize the more efficient form of transit.
