My wife and I spent a few years in the Houston Porsche Club of America doing their work to drive program, working corners one weekend then driving in the Drivers Education the following weekend. Let me further preface this story by saying my wife is not the best driver. Just ask our garage, fence and numerous other people's bumpers.
So this Friday a deer jumped out in front of us while she was driving and doing about 60. She slammed on the breaks, got the ABS going, veered right - deer went right, veered left - deer went left. Kablooie!
Indeed we hit the deer but I was damn impressed. She did everything they pounded into her head there. Break heavy and immediately; no sharp, sudden movements. I think 80 percent of the populous would have yanked that wheel and left themselves upside down in a ditch.
I think any kind of high speed training is important for anyone who's planning to be on the highway. Getting a feel for a car at its limit lets you know what you can and can't do.
Please give autocross or something like this a try.
