Cool. But sometimes the road is just plain impassable. And having grown up in many Iowa winter blizzards, I still don't trust even electronic systems. They help, but sometimes there's nothing you can do when there's basically no friction.
Humans deciding to go continue driving in such conditions is a mistake, leading to more collisions. Perhaps there will be a manual override, like "Unsafe conditions, voice password and waiver required to continue in manual mode; you might die or kill someone else."
Or take a page from the internet playbook: Destroy the car and re-send from the origin.
