(ELI5) Why do school busses have such a large overhang from the rear axle? There's at least 10 foot of school bus after the last tire. This seems odd, especially considering a semi truck has several axles spaced out and one near the rear.

The only real advantage of this is the busses' turn radius. With a shorter distance between the front and rear wheels, the turning circle of the bus also shrinks in size.

Weight distribution is less of an issue here. The engine in the front is heavy and the rest of the bus is mostly empty space. The axle could be placed anywhere between the center of mass and the rear end.
