I wasn't even aware of the notion that people in Russia know how to drive.. : (

Seriously, there are quite a few reasons it is difficult to drive well in 
conditions like these (Atlanta, GA). (I think) I can tell from Terry's dashcam 
video that the road temperature is below freezing, and the snow seems pretty 
dry (well below freezing, with little water content). These by themselves are 
the good news, they don't affect driving much.  If, however, there is a lot 
of moisture in the air (not to mention Freezing Rain) and the road is subzero 
(is that term known to Fahrenheiters? I mean below freezing), it will slowly be 
creating an extremely slippery ice+water surface. See 
http://en.wikipedia.org/wiki/Freezing_rain. I should point out that in Sweden 
(where I live), there is quite some variation in what winter conditions mean. 
 In the North, where they ALWAYS have snow in winter, the snow tends to be dry 
and packed (not terribly slippery). In the South, they USUALLY have snow at 
winter, and the temperature is always oscillating at, or slightly below, the 
freezing point. Treacherous. Oh, here's a reading suggestion : ) 
http://en.wikipedia.org/wiki/Miss_Smilla%27s_Feeling_for_Snow

I lived for a couple of years in south-east England, UK just a few years ago, 
and clearly noticed the collective behaviour that helps create this type of 
traffic jams.  At work, people would sit up in shock and stare at the large 
snowflakes falling, and then after 5 seconds thought (or maybe 5 minutes) scram 
for their cars. (The 5 minutes pause was probably the process of coming to the 
conclusion that it was in fact late enough in the afternoon to leave work.) 
So definitely, the relatively smooth, flat departure-time bell-shape has become 
much more pointed (higher). That's no good. 

In the UK, I realized, tyres are no big deal. Just stick'em on and forget about 
them (I'm exaggerating I know). The effects being that a lot of people are 
driving with pretty worn out tyres, not to mention pretty OLD tyres (aging 
makes the rubber harder). That's no good. In Sweden, people change tyres twice 
a year. (At least those who use studded tyres, which means most cars, but it's 
coming out of fashion..) These people will actually be _looking_ at their tyres 
properly twice a year, make sure they are properly inflated at least twice a 
year, and will generally be quite aware of how old they are. (Then there are 
year-round M+S tyres of course. (Mud+Snow.) But that's a different story ; )

Then there's culture. Despite being quite close, geographically and culturally, 
people in the UK and Sweden drive quite differently, especially when it comes 
to speed.  I noticed that the English may be more gentlemanly in traffic, but 
they sure drive much more aggressively (fast).  Not that they are breaking the 
speed limits all the time, but it is generally accepted behaviour to travel at 
a higher speed on a given type of road.  I could often tell where roads were 
narrow, winding, and generally dangerous, but people around me were driving 
as if they were any straight, ordinary roads. That's no good. Definite culture 
difference. If you haven't already seen this viral one-minute masterpiece,

When this happened to me, I left the car on a side street or the parking

That did not work out well in pre-modern Japan where the samurai carried
swords. There were severe penalties for using them. Granted it was safer
than most other medieval societies, especially for women travelling alone.

It did not work out well in the 19th century wild west where people often
carried pistols. Actually, in most towns such as Tombstone it was against
the law to carry guns. In Canada it was against the law in all towns and
cities back then. They had a much lower crime rate, and a lower murder rate.

Growing up in Colorado, I've come to respect any ice that might be on the
road.  A note to all the cold-weather novices who are out there driving --
try to get a sense of whether there is black ice on the road (i.e., the
road has ice on it, but it doesn't really look like it does).  If it does,
drive slower than you otherwise would.  If you drive too quickly, you can
easily send your car into a 40-mph tail-spin as I did once.  It ended well,

It's both, Jed and Stewie.  People panicked but they were driviing
slow when the density was low as is evidenced in my vid.  I should put
the whole drive up.  I made the trip quickly because I drove 60 mph
while traffic was travelling at 40 mph.  I wove in and out in the
gaps.  I'm sure that I looked crazy.  People thought the roads were
bad but they weren't.  The density gradient was compressed as a
result.  The roads weren't emptying as fast as normal; so, like a
tsunami, the gradient increased rapidly.  And, as the roads actually
became slick, the motion stopped.

At one point midway through it all, newsmen measured the flow rate.
It was 100 ft in 40 minutes.  Hence, a disaster resulted.

6-8 pm, 33 degrees at 3 PM when I left, 24 degrees at 8 PM, most of the
drop happened when the Sun set. I think the first few hours of delay were
due to volume, then once all those people became jammed on the highways, it
all turned to a sheet of ice.

 Approximately what time was that?

That is what I recall. I said it did not freeze until 5 or 6 p.m., which
was sundown. There was snow but not a lot of ice. I don't know about the
main roads. I was walking around on the side roads. I did not try to drive
after 2 p.m.

I guess so, but the total volume of traffic on the highway should not have
been more than any other rush hour. Granted, offices let out between 4 and
6 usually, and they all let out at around 1 or 2 p.m. You would think there
would be a queue on local roads waiting to get onto the highway, but not
much delay after that. However, Terry observed people going slower than
necessary on the highway, before there was widespread freezing. That would
explain it.

The cars melted the snow from 12-5 and then it all froze to ice over the
next couple of hours

Here is why Russians have dash-cams. I think these are mainly Russian:

So much for the notion that people in Russia know how to drive in the snow.

Two final notes.

A friend of mine who is a pharmacist at the hospital says that essential
staff was ordered to stay there yesterday and today. She and doctors slept
in empty patient beds.

Fortunately, there was not a single traffic fatality in Atlanta yesterday
or today. More than a thousand accidents but no one killed.

I averaged 2 miles per hour for 9 hours.  I walked the last 1/4 mile
faster.  Hard to get in a severe traffic accident at that speed
