Are Performance Driving Schools Overrated?
Local street driving schools have a core curriculum primarily centered on helping students pass their test, not on controlling their vehicle.
A performance driving school, however, do not happen on public roads. They're typically on a race track, or sometimes a big parking area. This enables the instructor to encourage students to find, and exceed, the limits of the automobile. That is extremely unsafe on a public road.
You figure out how to discover the limits of one's vehicle, and ways to get the most as a result. You learn that a few of the items that people often find somewhat counterintuitive, like smooth and silent tend to be more or less always faster than squealing and screeching.
What can you learn on the track that means the streets?
A performance driving course is a good thing, since it explains more about how exactly to read your vehicle and the street which could ever be tested in the typical 5 min driving test people usually take when obtaining a licence. But don't take that sort of driving to the road because the remaining general public will not learn how to respond to it!
