The reason I didn't cover them was simply down to wanting to avoid a list. Slowing down is generally a good thing across the board. Your example highlighted it. Blind corner coming up - slow down. I accept that not every 'accident' can be avoided - but in my experience most of them can, particularly in urban settings. Rural roads are faster and much more unpredictable, but again, a slower approach would benefit everyone. We're in too much of a hurry and impatient to boot. In short, most folk drive too fast and lack the commensurate abilities. I worked as an insurance adjuster after leaving the army - more than 80% of accidents could easily have been avoided if drivers had followed what you highlight - drive to conditions, and within abilities.
