You have to expand your criteria of what makes an idiot Wing. I have had many cars on all-seasons in winter, in Calgary. I have even driven them into the front ranges to go skiing on a nice stable day (the horror). I think you should modify your statement to: Anyone who drives in winter conditions on all-seasons is an idiot.
In Calgary we can have nice stretches of weather in the middle of winter (10 degrees Celcius and dry roads.). During these times sometimes you will see the second or third car make a short appearence. During these "summer breaks" even top down convertables make an appearence. When the nasty stuff hits I revert back to the Dakota on winters and the convertables dissapear....
