I've recently noticed that they are not folding at the most appropriate times for me, but I'm not sure if this is new behaviour or not (and I turn the feature off for the winter season).
It seems logical to me that as driver I'd want them folded as soon as I exit the vehicle, eg. so that I can get out of a tight parking spot. I've had to press the manual button a couple of times recently to make sure they go in (oh the agony lol)
