Los Angeles just needs buses that come through frequently enough to obviate the need to check the schedule. Also dynamic bus routing, which would reduce the total number of buses required for this.
Buses have a fundamental speed issue that subways do not because subways do not stop at intersections for cross traffic. At LA's vast scale you need a subway, possibly even express subways.
