Watching that video (1067) reminded me of my Driving lessons with Tony(?) Palmer back in 1967/58.
He had 2 main principles,
1st If you want to lean to drive that is OK, if you want to scrape through the test go somewhere else.
2nd There is no such thing as a dangerous road or car only a dangerous driver.
Drive to suit the conditions then the road is safe i.e. adjust speed to suit conditions which includes stopping. A car is only dangerous even no brakes and/or faults to other parts if someone starts to drive it.
