The statement is absolutely correct. A plowed street can be worse than
unplowed, especially if there is packed ice underneath.

I have to agree with RB.

Now Bob.... don't bait Bobsprit like that. We both know that if there is ice
under a snowfall... it's an Ice Road.... and the three requirements are to
be able to make progress, to be able to direct progress and to be able to
halt progress.

Certainly if your "SUV" has a 12" clearance and you drive into 24" of
snow.... stopping will not be an issue..... progress and direction will come
to an abrupt halt. If the same vehicle encounters a low traction area... a
simple reduction of speed will allow all three factors to be retained and
safely make directed progress
