It's easy not to go fast. It's not so easy to avoid spinning and sliding, however. At 35mph up a lengthy hill, my A4 V6 Mustang began spinning the rear tires like I've never seen before. My actual speed dropped to probably about 20mph before I finally got past the ice patch. No car is safe in the winter, but some are less dangerous than others. Don't drive a RWD car that has more than 250hp in the winter, because you're just asking for trouble. Besides, Supra's are very hard to replace, and you'd hate yourself incredibly if you wrecked it driving in bad weather.
