how about when the doors pop open in a jump/crash/bump and we contiunue driving and the close themselves while cornering or during rough accelaration
Often during a crash if the doors become open, it's because the door frame is so bend or other mechanisms (locks etc) are damaged which prevents the door from closing. A part from that, the doors, hood etc open up way too easily so the most realistic thing would be that they are jammed after a crash. However, if I remember correctly then the team is already aware of this issue.
If your door opens because of a crash it is because the locking mechanism was ripped apart. It is pretty impossible to latch it after that.
Sometimes yes, most of times no as @FS16 mentioned. Either broken locking mechanism or the frame is so bend that the door won't fit there anymore. However, it would be a nice feature for when it's possible to open/close doors officially.
