I fold my mirrors every time I cross a bridge over here. I've seen many mirrors get smashed off from mirror on mirror contact with semis and other vehicles cause it's a super tight bridge. I love having that option to close them while driving.
I just got my Rebel, a 2017, and I am obviously still learning it. They should have the option in the uconnect settings to have the mirrors fold when turned off and on automatically, with the option to manually override at anytime. They should also have an option to have all windows close when turned off as well. I have to check again but I think it doesn't have the mirror tilt in reverse option either?! Are these things that can be updated in software updates? And why tf can we not access uconnect mobile in Canada? Up here in the cold it would really help to be able to remote start from a cell.
There are devices you can buy that install as modules to do exactly this. With a little more intelligence, too. I can't vouch for the reliability of any of them. But there are companies selling these things. You can find them on Amazon and other places.
