Nothing surprises me on aircraft these days. The number of people that take absolutely no notice of the instructions from flight crew is way out of line.
I can't count the number of occasions that passengers are standing up and getting their bags from the overhead lockers while the aircraft taxis after landing, despite specific announcements to the contrary.
In a study released on Thursday by two industry groups, the Airline Passenger Experience Association and the Consumer Electronics Association, as many as 30 percent of all passengers said they had accidentally left a device on during takeoff or landing. About 67 percent said they had never done this, always ensuring that their electronics were turned off. Four percent were unsure.
In another segment of the study, passengers were asked if they turn their devices to “off” when instructed to do so by the pilot. Although 59 percent of passengers said they do fully turn their electronics off, 21 percent said they often simply switch to “airplane mode,” which disables the main radios of a gadget. Five percent sometimes adhere to the rule. And others were either unsure or do not carry electronic devices on a plane.Study: Almost 30 pct of Air Passengers Leave Their Electronic Products On All The Time [bits.blogs.nytimes.com]

Planes should really be able to cope with a little interference. If they cannot, its a serious design flaw. The implication is that planes could be deliberately crashed by high interference (after all, mobile devices cause comparatively little).

Not a good analogy because there is not practical alternative to having some sort of signalling system on the roads.
Planes should be designed to cope with interference regardless of what passengers do with their electronics because there is a lot of potential interference from outside: cell phone and radio transmitters, solar flares, radar, and lots more.
Then there is the possibility of deliberate sabotage from inside or out.
