Motor braking effect of the four-stroker – does anyone else know how to use it meaningfully?

Hi, admittedly, the title of this thread seems a bit provocative, but what I have experienced in my Austrian holiday in series this year makes me believe in certain deficits in driving school training. Since vehicles drove down passport roads and stood three quarters (!) of the track on the brake. That not one or the other in the lower part has landed in the guardrails because of braking fades seemed like a miracle to me. Others in turn turned out the gears between two turns, around before every turn to convince yourself of the effectiveness of their ABS… Is it no longer taught today in the driving schools that one should go down a mountain in the same aisle in which one went up? That then before every turn easy tapping of the brake is sufficient? That among these “permanent brakes” also coaches were to be found, seems to me particularly worrying.
