Even if a bus-only lane is empty some of the time (maybe even 99% of the time) it can be more much efficient than a car lane in terms of passenger capacity. The density of passengers per vehicle or per meter of roadway is much higher in buses and the buses are likely to move faster when they don't have to weave around cars.
It might be a bit counter-intuitive, but having one bus drive by every 2 minutes on a lane that is otherwise empty can amount to more capacity (maybe ~50 per minute) than the case where the lane is full with gridlocked cars with one person each (~30 per minute, i.e. one car every few seconds). With trains the difference is even greater. The Yonge subway line in Toronto has only one track in each direction and any given segment is free of trains most of the time but it carries around the same number of people as the gridlocked 12 to 16 lane 401 at rush hour.
