I want to echo this sentiment - I'm transplanted from NY, eventually ended up in Atlanta, GA. I drove many winters in NY, and being the youngest of four I learned a lot from my parents and older siblings about driving in the snow. I can tell you that no matter where you grew up, how great a driver you think you are, or what vehicle you have, driving on solid ice is not just difficult, it's treacherous. Add in all the hills we have around here, and you're really screwed.
Now; first "snowpocalypse" from two weeks ago: it started snowing mid-morning. Around noon, people realized they'd better start getting home. By 12:30, the roads were ICY (not snowy); it's very hilly around here and many vehicles couldn't make it up hills. This caused massive gridlock; even people with 4WD, AWD, and yes, FWD that could have made it were stuck in the gridlock anyway. This all happened before the local and state governments could react... there were vehicles out salting and sanding, but they didn't get a chance to hit even a fraction of the roads. The traffic map on the GA511 website went from green to black in a half hour. Yes, I largely blame ignorant drivers who don't know what to do... all those mid-level pickups and sports and luxury cars with rear wheel drive, just sitting there spinning their tires (they didn't realize after a few seconds it just wasn't working? Unbelievable). The number of idiots trying the same things over and over again, getting worse and worse results was baffling. Once I got past a few gridlocked areas I made it home just fine with my FWD car... but the way I get out of the city is largely level once I'm away from the mid town area. Other interstates aren't so "lucky," virtually everywhere there was a hill there was gridlock. And yes, while I blame the drivers, the "pros" were no better - the biggest problems I encountered were buses and trucks which, when they spun out, blocked the entire road.
Fast forward to this time, and all the gun-shy drivers just stayed home. Up in North Carolina they experienced the same problem this time that GA felt last time, and I won't belittle them about it. In GA, with everyone warned to stay home, the service vehicles are able to salt and sand the major roads. I want to make this clear - people didn't know last time how bad it would be, the storm was supposed to pass to the south and it shifted north. Even when it started snowing it was not icy, it was just snow... it just didn't last long. Everyone from schools, to private and government employees all left at the same time, when they realized it wasn't going to let up. A lot of people blame the government... I don't. They had trucks ready, it was just a bad confluence of events and eventualities that led to a bad situation. There was really nothing they could do. Even the supposed idea of staggered release times (first schools, then private businesses, then government) is ridiculous - and it's the fault of the people, not the government, because as soon as schools get released, everyone tries to rush home to beat the traffic, it's just the way people are (not all of us, obviously, I waited until late evening to even try to leave).
The other BIG difference between this and last time - and this is how it usually is - the problems didn't start until Tuesday NIGHT, which means most people were already home from work. When it hits mid-day, people are already at work and screwed. Usually these accumulations happen over night, we wake up, and say "snow day!"
It's like any other weather event; they can be unpredictable and catch people off guard. It's just the way it is sometimes... sometimes the best laid plans work, sometimes they don't.
