In such case the density would probably be large enough to efficiently match e.g. 4 people to a car. Commutes are predictable (people do the same exact trip at roughly the same time) so easy to optimize. You can therefore pack more people in the same fleet during peak times than during non-peak times. The second obvious step is to create additional fleet made from half-buses like the 12 seater for peak traffic, a better Chariot.
