> a bus every 10 minutes is effectively 500-900 meters long!
uhhhhhh what. What does every 10 minutes have to do with this at all
> It easily "takes" as much space as 100+ cars.
are you ok??? have you seen a bus before??
> A single bus needs about 3 drivers to be effective
I have never ever seen a bus with 3 drivers in it. If you're talking about 3 drivers over the course of 24h, those drivers are not in the bus at the same time, and therefore don't make up 20% of the passengers on the bus. If you're saying the average bus route serves 15 people per day, you are certainly mistaken.

See the word "effective". Think about the road space that a bus requires but doesn't use if it is just once per 10 minutes.

Yes, I'm talking about the drivers that are needed for a reasonable 16-hour bus service. And the typical ratio is actually a bit more than 3 drivers per 1 bus.

No. I'm saying that on _average_ there are 15 people in a bus. More during the rush hour, fewer during the off-hours.

Excepting the case of a dedicated bus lane, the amount of road space a bus is preventing other cars from taking up at a given time is equal to the size of the bus. Technically, it's less than that in the case of bus stops littered amongst parking. In the case of a dedicated lane, it reduces the maximum throughput of the thoroughfare, but it's not a simple thing to model as there are other effects that the bus can have to reduce the number of cars when the rate limit of thoroughfare would be pertinent (i.e. usually rush hour). Just saying "think about it" when saying a bus takes up the space of 100+ cars doesn't really substantiate such a bold claim.

If there is an average of 15 passengers on the bus during the operations of the bus and there is an average of 1 driver on the bus during the operations of the bus, then it is 1/16th occupied by driver(s). For it to be taken 20% by driver occupancy, then it would require there to be an average of 4 passengers on the bus during operations.
I actually am citing the traffic engineering handbook, the section about computing the efficacy of bus lanes. And I'm using deliberately conservative estimates.

No. For the bus to be viable, all 3 drivers have to be "virtually present" there. A bus _has_ to be available at all times with a reasonable interval, otherwise it might as well not exist.
Or in other words, a passenger needs to be paying the salary for even the missing drivers.

Not all buses require a bus lane. A bus lane is a deliberate choice that doesn't make sense in all areas and for all bus routes. It is disingenuous to reference the reduction in throughput due to a bus lane as a blanket claim that an individual bus takes away the room of 100+ cars on the road.

Your claim is about how much of the bus is taken by drivers, which while having some correlation to cost, really doesn't have anything to do with the cost of operating the bus. An oversimplification of this is to posit a magic bus that runs 24 hours a day with 8 hours shifts by 3 drivers. That means that the drivers take up 24 person-hours of capacity on the bus. If we say they have 15 passengers on average, then the passengers take 360 person-hours of capacity on the bus. Thus, drivers take up 24 / 384 or 6.25% of the capacity.
Honestly, I never really cared enough to convince you that transit is a good thing because that feels like a fool's errand. But these weird claims and fallacies bother me. If you want to claim that a bus isn't cost effective, then great. Just cite an actually relevant metric and actually calculate it correctly.
