Also, while this isn't quite the same scenario, if you have a vehicle
with power steering and power brakes, and the engine suddenly stalls, you
still have steering and brakes, you just have to exert more muscle
power. This has happened to me twice, both times just as I entered a
sharp curve. I made it around the curve, stopped the car, and succeeded
in restarting the engine.
If they ever go over to an entirely drive-by-wire system, with no
mechanical linkages between the steering wheel and the steering
mechanism, or the brake pedals and the brakes, then the car will be
uncontrollable if the electrical system quits working.
