I was driving in freezing rain (no winter tires) at 40mph and was getting coated in shit from passing cars which made it nearly impossible to see. I tried to slowly move up to 50mph so fewer people would pass by and spray me. I fishtailed 3-4 times - thankfully no one was in the adjacent lanes - and I quickly recovered. The experience scared the crap out of me so I parked my car and ended up buying my ex-girlfriends '03 Mazda protege a week or two later.
Here I am 3 years later and I've got a long ways yet to go on the Z. I can tell you that it won't see snow again though.
