The part I quoted is so true.
I see people do retarded things driving all the time. During the winter, on a slick overpass 2 winters ago, I saw some woman trailbrake heavily on an turning overpass. I was coming towards her, saw he nose dive when she was braking and KNEW what was going to happen. Sure enough, the back end shot out and she swerved across the road and blasted into the overpass guardrail.
I was already completely stopped by the time she impacted the guardrail because I knew she was going to lose it because she did exactly what you never do in limited traction situations, which is brake in a turn.
I have been autocrossing since I was 18 years old, and that benefits me in so many ways. Firt off, it gets aggresive driving out of my system in a safe, legal environment. Secondly, you learn the actual limits of your car, AND your ability. Even small things like a deer running in front of your car, which could cause serious injury and damage, can better be avoided. You learn what you can and cannot do with your car in emergency situations, and I've found it makes me a more defensive driver on the streets.
"What is Solo II?
"Solo II is a precision sport, much like, say, archery, riflery or golf. You must be precise and consistent, all the while driving so fast you can barely concentrate" -- Mark Sirota
Solo II events (also known as autocrosses) are an all forward motion driving skill contest. Each driver is individually timed to the thousandth of a second, over a short, miniature road course clearly defined using traffic cones. Cars compete one at a time, hence the name "Solo", in a class with similar cars. An event can be held on any flat paved surface, usually a parking lot, or airport apron or runway.
Solo II emphasizes driver skill and vehicle handling rather than just speed. The corners are tight, and there are lots of them, so the driving is exciting and challenging. Solo II speeds do not exceed those normally encountered in highway driving. (This is the main difference between Solo II and Solo I; where much higher speeds are attained)
The skills you learn and practice here; smooth transitions, enhanced braking, and skid correction, will have an immediate impact on improving the safety and skill of your street driving. Solo II is an excellent way to teach car control to young drivers in a safe environment."

If you have an local SCCA club in your region, go participate in one no matter what kind of car you own (as long as it's safe to drive, and no SUV's due to the rollover risk). I started in a 1992 Toyota Camry. Noone will laugh at you, and you will have a blast while learning a ton.
