Off topic, but I’ve literally had this happen before. And what part caused the mid-drive switch off on my way to work, you might ask? Why, the anti-theft system, of course!
A shoddily designed 2 cent wiring connection between the security fob in the key and the car’s computer would fail, and since said connection lived somewhere accessible only through several hundreds of dollars worth of labor, the price of the design flaw was essentially subsidized by the end user. Definitely a safety hazard with a car, but I can’t say I’d be tremendously pleased if I had to likewise deal with it with my notation software. My condolences
