Well, finally, my update notice popped up while driving, and I clicked ok and forgot about it, so I made a quick stop to pick up milk when I came out, the car was updating. Got stuck in the parking lot for almost 3 hours.
I only have myself to blame, but I thought there was a way to cancel the update. I did not find any way to stop it
Omg
But this cannot happen only because you clicked ok while driving. The Update should only beginn when you get the second warning after you parked the car and you also confirm that with the "install button" on the right. See my photo.
