NAC: Icy Pileup in Montreal...What Lessons to Learn?

[Einhorn Hofmann]

This video made the rounds locally last week, not sure if anyone else saw
it:

The major blame seems to lie with the city for not spreading abrasives or
salt on a steep hill before the Monday morning commute.

However once faced with that icy hill, its interesting to analyze which
vehicles crashed, and which ones avoided the crash.

Several vehicles just totally locked up their tires and lost all control.
First a bus, then a white plumber's van that appears to be a Ford, then a
second bus, then a police car (Dodge Charger), and finally a snow clearing
vehicle.

One vehicle that easily escaped the crash was the green taxi.  You see the
wheels don't lock up, the driver manages to retain some control, and turns
away from the crash site.

I'm wondering if all the vehicles that lost control don't have anti-lock
brakes.  Would they disable anti-lock brakes on a police cruiser?

Or is it FWD vs RWD that made the difference?  The taxi is FWD, the bus and
the two construction vehicles are RWD.  But the police cruiser?  I know
some of those Dodge Chargers are AWD.
