I absolutely agree that everyone was driving too fast for the conditions. I was just pointing out the range of it. You'd expect there will always be some people a bit negligent in a flash snow or ice storm and end up with some minor impacts, but others were going way too fast and ended up creating "crash clusters" risking the lives of others.Even minor fender benders mean that they were either driving too close to the vehicle in front or too fast for the conditions and thus unable to stop in time. Yes things can happen quickly but the more time you give yourself by either driving slower or having more space between you and the vehicle in front the more likely you are to prevent a collision in conditions such as those.
When it snows or sleets, all bets are off on "trying to save time" getting somewhere. Top priority is to keep traction, so you go slow and extend anticipation of traffic and turns hundreds of yards ahead. Space between cars needs to extend 3 to 5 fold above 10 mph. In all the years I've driven, I've never had an impact with another vehicle in snowy/icy conditions. In first few years of having a driver's license, I slid partially or fully off the road a couple of times and learned plenty enough from that to always abide by "snow means slow". If someone is driving too close to me, I'll pull over and let them pass--don't want to risk them smacking into me.
