In a sense, I agree that it makes sense to train people to be better technical drivers. The issue is that for avoiding accidents, your time is orders of magnitude better spent practicing planning and avoiding potential situations in the first place.

Being able to see where you need to pay extra attention, what cars to keep extra distance to, and being able to judge what a safe speed is saves far more lives than building the technical skills to get out of a situation once you’re in it.

To be fair though: at least in Norway we have an obligatory course where we drive on sleet/ice or oil to practice controlling a car in winter conditions. However, the main focus of the course is on recognising how fast you can go in different conditions, and how far of a breaking stretch you need to plan for.
