People taking the bus is the entire point.

It's also healthier than those people going into a car, since more people in buses means fewer cars on the road, and correspondingly, less pollution, and correspondingly - fewer roads and parking spots are needed. Which in turn frees up space to live, enjoy nature, and life.

If you want to motivate people to walk and bicycle, you will also need to foster a good public transit infrastructure: that'll enable walking and bicycling in other cities. After all, who will walk to another city? You walk to a bus stop, take it, then a train, and then you walk.

Way easier than spending precious minutes on searching a parking spot and being miserable in a traffic jam, stressing about other drivers, and so on.

Subsidised tramlines are a solution. With public transit lines being added, people will also flock to living near those.
