WOW what a bunch of prudes!
I saw nothing wrong with the way you were driving, you weren't throwing it sideways everywhere you went, and there was no traffic where you did decide to break traction.
Believe it or not, the Supra is an extremely capable car in the snow, I remember driving mine in a storm that we got 6" of snow and I only had Goodyear Eagle RS-A tires on the car, not snow tires. I can only imagine how much better it would be with snow tires or even studded snow tires.
The people that "don't go full throttle" or "don't go out in the snow" are the ones I hate to be driving around or near when it decides to snow.
8 Posts about how bad it is to drive like that... Feel like this forum is full of old ladies sometimes.
Scotty: Good driving, good video. Post up some more! (what camera did you use?)
