They do make an effort to make it hard to do safety critical stuff by accident though in cars, small planes and jets. Like in a car it's easy to mix indicators and windscreen wipers which are on various stalks but turning off the engine and locking the steering is very different action, on traditional cars turning the key and taking it out. Similarly here the fuel cut offs are obvious levers that have to be pulled out before they can be moved.
