"except with hindsight you can usually work out why"
The significant characteristic of hindsight is that it comes too late.
So, yes, I can see why my car does phantom breaking by detecting oncoming traffic in the other lane on a bend. It wouldn't help in the least to know that if I were shunted by a following vehicle whose drive, quite reasonably, didn't expect that.
The really frightening one, fortunately without actual braking, was the flashing collision detection lights on a curved section of motorway. As far as I could see the only thing responsible must have been detecting the supports for the centre barrier. It also, BTW flashes them under braking approaching a T junction if it takes a dislike to a wall or hedge across the road.
What's needed isn't hindsight by the driver, it's foresight by the designers because AFAICS this stuff isn't really ready for use on the roads.
