I think a well designed winter specific FSD system is probably more safe in snow and ice than a human. For instance downshifting to ensure wheels continue to spin on slippery surfaces, subtle corrective steering to keep the vehicle within its lane, etc. should be easier for a FSD car since it won't panic and over-correct like most people do in those situations.
And if the car reduces speed when appropriate and some assholes start tailgating it, it won't suffer the anxiety of holding up 10 cars that want to drive beyond the safe, reasonable speed for the snowy/icy conditions.
