The Fit is a blast to drive but I must say I enjoy snowboarding more, and I don't know about lateral G's but spinning in free fall for about 100 feet off a mountain with 10,500 elevation is way more intense than any car ride.
I was in Salt Lake in February and took black diamond trails for the first time, there are drop-offs and turns that you have to be ultimately prepared for to avoid death, it was wicked fun! With snowboarding you can go as fast as you can handle--it's really more about braking all the time so you don't die, but if you take a straight with just a slight carve to maintain stability you can easily go what feels like 80MPH, on elevation so drastic that if you lean too far forward it's all over.
