I have noticed the wider arc opening faster than tighter arc (avoidance mode), makes sense since sensors are monitoring, but in the case of closing, a faster door will do more damage especially if someone is in the way. I vote for tightest arc and slower close if that is not already the case. I don't have my car yet but I will be checking these parameters once I get it and possibly making some recommendations if it is still an issue by then.
Hmm. The FW door sensors are pointed at the sky, but you still have the side looking ultrasound at the front and rear of the car. What if it checks before it opens, makes a record, and checks again before it closes the door - and if it sees something new on either sensor (or even something gone?) it defaults to tight arc?
