I remember an old SAGA magazine article from fifty years ago, in which it was said perfume or cigarette smoke could make a computer choke.
We used to make them choke and stop, at a company I worked for in the 1970s. Light a cigarette, hold it near their air intake, and them machine would choke to death, and then we would have to “reinitialize” it, wiping out all the stored data on the computer.
I was thinking it had to related to smoke or carbon monoxide activating a detector of some sort. Strong perfume is really nasty stuff, but disabling a modern car is quite a feat.
