Switched system with 2 modes: 'left', 'right'.
Modes are controlled by the system.
States are controlled by the environment.
So only control over dynamics is through mode switching.
Transitions are thus interpreted as non-deterministic.
This can model uncertain outcomes in the real world,
e.g., due to low quality actuators or
bad low-level feedback controllers.
