Or you could simply not own a car anymore, but order two robotaxis to drive you to work and your kids to school at the same time (with optional carpooling to reduce costs) - that would reduce both traffic and the need for parking space.

the concept can be scaled up to something smaller than a bus (let's say 6 pax) that you hail like uber pool. As the technology becomes commoditized it can be applied by metro transit authorities to run smaller buses with much shorter headways.

Traffic is mostly caused by bad drivers. Eliminate those, raise speed limits for robocars, and lanes can be narrowed/removed.

True that if all vehicles were autonomous and coordinated then traffic flows could be increased (though by how much is debatable). However, as with building more lanes, you run into the issue of induced demand, where as you speed things up more people want to do it so you are back to congestion.
