For me, the question is 'is there a bug?' Because, if there is, then we should be all up in arms for it to be fixed.
However, if it only a problem with your car or your usage then to tar the whole brand with that fault is not correct. I am always keen to find the reasons for a perceived fault and to seek solutions in case I end up in the same situation.
As I said in my previous post, I have used the pull-up parking brake, having inserted my seatbelt at the start of my drive, with no problems. So the jury is out on whether your car has a problem or mine.
Leaving a problem 'in the air' should not be a solution.
