Thanks for putting these hints which are invaluable !

I would put more emphasis on the first hint, which is the most important.
You could even replace “conditions you are in” by “what you can see” :
– road surface (wet, slippery, with small obstacles…)
– places from where something can come without being seen

I say that because many ppl drive very fast on road they know well.
But even if the conditions are good (weather), there can still be some oil (or an anything unexpected) in a turn we can’t see…
