Car control clinics give you firsthand driving experience on dangerous roads
A car control clinic is typically a one day, hands-on course that teaches drivers (usually teens, but often people of any age can attend) the basics of, well, how to control their car. For example, students drive in circles on a swath of concrete covered in soapy water to actually feel what's it's like to spin out.
Students drive the same car they drive every day, and it hard-wires their brains with the do's and don'ts that most fully licensed drivers never learn. That's hugely important, because while knowing the theory of how to recover from a spin or drive on a slippery surface is better than nothing, it's another thing entirely to have actually done it. The same thing goes for emergency lane changes and sudden stops.
According to the National Director of the Street Survival course, "As of September 2015, 73% of the students that have taken Street Survival have not had a driving incident. Of those that report experiencing an incident, 80% indicate that they were not at fault." Given rates like that, the fact that proper training isn't already a requirement is beyond absurd.
