This is related back to us by our students time and time again. When we do receive some of these comments from the students and you see the big smile on their face at the end of the day, it sure makes all the work worth while. Yes, I can see it improving, but only slightly and not nearly enough. You can show someone what is required, but it does not mean they can do it until they practice it over and over until it is second nature. They have to feel what the vehicle can and will do, not just see what will happen.
Drivers can learn what the traffic signs mean, where to stop, how to signal etc.
What they really need to learn is what they and their vehicle are capable of when that emergency situation will arise, and it will, for everyone. We have found a secondary benefit to our course in that many of our timid drivers have begun to see that driving can actually be fun, once they realize they are in charge of their situation. There have actually been drivers who have decided to go on into competition driving after they have done our school. I am a firm believer we are building safer cars but not building safer drivers.
