Busses get 3 miles per gallon max and have typically have only 6 passengers,
so that is 18 passenger miles per gallon.

That is exceedingly low, 18 compared with 470.
the car is 26 times more efficient than the bus

Bus costs 220,000, car cost 15,000

Bus maintenance per year is 7,000
Car maintenance is 200

Bus driver costs 65,000 per year

In 10 years the bus costs 220,000 + 7,000*10 + 10*65,000 + (100,000
mi*$2/gal )/ 3 miles per gallon = $421,666

In 10 years the car costs 15,000 + 10*200 + (100,000 mi *$2/gal)/235 mile
per gallon =
$17,851

So the lifetime cost of the bus is 23 times more than a car. Therefore the
bus would ave to carry at least 25 people simply to break even with using
cars.

An then there is the pollution factor, busses generate far more pollution
than equivalent number of cars.
