Do Standard Mirrors Manually Fold Back??

I'm going to be moving into a new house soon and when I took my 197 to the new house to trial fit it in the garage there wasn't much clearance between the mirrors and the garage door frame.

Don't get me wrong , the 197 fits in nicely enough but I was wondering if the standard mirrors can be folded back by hand to give myself some extra room so that I don't have to be ultra careful every time I manouvre it in or out.

I've had a quick go and they seem fixed so I don't want to force them without knowing if they are meant to fold in or not.

Cheers in advance!
