Given that different people have different heights, there seems to be for myself no reason why every chair in a bus has the same height.

There could be different rows with different height and in an uncrowded bus people could select the height they like best.

Is there a good reason to have uniform height?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.If this question can be reworded to fit the rules in the help center, please edit the question.

Not sure this is a UX question as much as it is a cost control/manufacturing efficiency/etc question. – DA01 Jan 17 '14 at 18:52
I second what DA01 said. It's probably has more to do with being able to manufacture the chairs in bulk at a lower cost. – flatfootdesign Jan 17 '14 at 19:25

Would you rather find a seat on a crowded bus or be coerced to wait for seats of the right size to become unoccupied? Keeping the seat heights uniform increases the mean number of users sitting comfortably at higher capacities.

In uncrowded buses, sure, different heights can be implemented. But that would involve higher manufacturing costs as you now need S, M, L and XL seats to be produced than a standard size.
