Re: I'm waiting for...
"What happens when the vehicle finds a nice ice patch..."
That's an existing feature on many cars, e.g. Mercedes ESP (Electronic Stability Program).
It fiddles with individual brakes, cuts engine power, blinks a light on the dashboard, and most often manages to keep the car straight.
Physics means it's not going to be a 100% solution. Which is why my car has studded ice tires.
Thing is, at least these systems generally obey the moral guidance 'First, do no harm' to a very high degree.
