Scary when that happens. I had an Acura Integra that used to spin out in the snow and ice -- you had to take your hands off the wheel and let it come to a stop. Fortunately, it was perfectly balanced, so would spin in place, not going into other lanes. Still terrifying, but not as dangerous.

And, tiny quibble from the math geek -- if the car did a 360, it's facing the same way it started. If it's facing back the way it came, it did a 180.
