Yep, my 23 Powerwagon will let me fold them in going slow, but not at road speeds. I was doing about 7mph and it let me, so 10mph or less sounds about right.It will allow you to fold them in under like 10 mph, any faster and they wont. I could fold my 2019 1500 mirrors in on the highway if I wanted. So this was a bit concerning especially with some roads around where I live, I like to fold them in when there is on-coming traffic like your example.
