I really want to see the data from the car. I haven't tested it myself, but if you ignore the warnings to apply turning pressure to the wheel for long enough, the car comes to a stop.

I haven't seen an incident either myself or on someone else's video where phantom braking will completely stop the car, but my speculation is that the driver was asleep or otherwise not paying attention and the car was bringing itself to a stop in the middle of the road.
