You missed the last and most funny one

>Driving a gyrobus has the added complexity that the flywheel acts as a gyroscope that will resist changes in orientation, for example when a bus tilts while making a turn, assuming that the flywheel has a horizontal rotation axis.

So you have a giant blender than can travel one mile in a straight line before needing to be recharged




There once was a train that made clever use of that effect: https://en.wikipedia.org/wiki/Gyro_monorail


Shouldn't it still be able to turn, just not tilt?


It depends what orientation you mount the gyroscope in, but yeah the "correct" way would be to make it axis vertical to limit pitch and roll
