Seems likely that we're missing the crowd control element. It seems likely that 46 people will be unable to ride the subway or taxis and arrive at a single destination at once. By blocking busses, onboarding and offboarding will not have the blocking behavior along with the other logistics of driving and parking large vehicles. To computing terms, it's likely less efficient for the people on the bus (a large blocking operation) though more efficient for parallelized split groups of people and if not directly, then at least in diversity of groups of people.
