Last winter I took my moms envoy out when it was snowing, since it was AWD. Well, I was on the highway doing ~30, it was slick as hell out and I was being cautious. Well, somehow, I managed to spin out and do a complete 360 on the highway coming within 4 feet of the center margin thing.

And I took her bmw up to 115, with her in it, she almost killed me, but she wasn't that mad, it was incredibly smooth at that speed.
