Are you serious?2 yrs ago when I actually saw ice on the roads (saw nothing last year...lucky I guess) I couldn't even get out from in front of my friends curb to go play in the huge parking lot up the street. Just rotated a few inches closer to the curb! I couldn't even spin out in the ice! OTH, we tried our hardest to get his AWD Explorer to spin out and barely got the back end to jiggle out a tad. A heavier car helps with traction unless of course you're hauling ass and hit a patch of ice or hydroplane, then it doesn't matter what car you're in. Especially if you have an aggressive alignment for track days, driving in heavy rain or ice is quite nerve racking in the Miata. I just put new tires on only a few weeks ago and it's still a chore to drive in really bad conditions like today.
