It`s totally possible.

My city excels at this. We are at level where bus system is not enough at all. But the municipality is trying to avoid it since it’s seen as politically tricky. Nobody wants to start it, take the beating and then let opponents cut the tape a decade later. The bus system is struggling too. Old buses, incomplete bus lanes and so on. When one jackass got an idea to reduce car traffic and started with adding obstacles to cars without improving public transit… Traffic did not better. And buses get stuck with the rest. Thankfully remote/hybrid work is all the rage. In recent decade quite a few offices and other workplaces moved away from urban core. That helps the situation a bit.
