So I get that modern cars have a "lane assist" feature whose job is to wrench the steering wheel out of your hands when you cross a white line to avoid a flood or (certainly in Cornwall at the moment) the remains of a fallen tree.

But when there's no white line in sight? As far as I can guess it's reacting to low sunlight reflected off a wet road.

FFS! If a system hasn't the remotest clue WTF is going on it should switch itself off, no? In preference to trying to kill people?
