I think it's fair to say that with the kind of snow/ice Crash is talking about certain areas of Seattle would have no choice but to pretty much shut down. Considering the size/incline of some of the hills, narrow streets, population density, street side parking, buses and pedestrians rule 0 may be the best to follow by many, whether they know how to drive in the snow or not, whether their vehicle is well equipped for it or not. That said I haven't ever been to Spokane or even spent a winter here in Seattle so I can't compare conditions.
There are some condition and road combos that are pretty much undrivable, yes. Generally very steep hills with super slick ice. But that isn't the case every time it snows in Seattle, and certainly isn't the case for the areas around Seattle. The Seattle mindset, generally, seems to be if it snows at all, what-so-ever, leaving the house is just madness. The number of times I saw Westside drivers with chains on in less than a 1/4 inch of snow at WSU was just hilarious. That and how often I'd get asked if Pita Pit was even open because it had snowed 2 inches.
My friend had to make a trip over to SeaTac a few years back when GEG was shut down to pick up his girlfriend. There was about a foot of fresh snow here and several inches on the Westside, but all very drivable and manageable. He said Seattle and the area was bizarre because of how many cars were just left on I-5 because it had started to snow during traffic.
Just one of those mindset things, like how some people think it is impossible to drive RWD in the snow, etc.
Good advice in here about driving in the snow and your best bets are practice and winter tires(which you don't seem to want).
Anybody drive with studs? I can imagine them making a pretty huge difference...
I use to drive with studs when I was much younger, but have found they don't offer much benefit 99% of the time and make things worse on wet pavement. Studs only make a difference on very solid ice, and even then a good compound and tread design will suffice. The rest of time, like fresh snow or plowed roads, they make things worse and just demolish the surface.
One thing to look out for, when trying to go up hills with crap tires sometimes it is necessary to really get them spinning, like up to 60-70mph
, just keep your eyes on the temperature guage!
Spin to you win!
It can help a bit but often you'll find you're not making any progress. I've found just keeping the throttle perfectly steady works out a bit better if you have a bit of a start because you're less likely to start spinning things. And while spinning can work, it does ultimately fail going up a hill in my experience.
