assuming control—similar to the soft protection systems in aircraft. Conversely, a
collision avoidance system, set up to intervene automatically in an impending col-
lision, is more akin to hard protection. Similarly, the intelligent speed adaptation
(ISA) systems discussed earlier in this chapter can fall into either camp. A system
which warns the driver that they are exceeding the speed limit, perhaps giving extra
resistance on the accelerator pedal, would represent soft automation. The system,
which overrides the driver’s input and will not allow them to break the speed li
