Why don`t the truck makers invent a mirror that can be folded in,so as the road narrows,and the mirror gets pushed in,you do not have to stop to push it back out again,when two trucks pass a bit tight,you press a button in the cab,so not to break the mirrors.
Because knob head truck drivers would still break them.
And because knobhead vehicle designers like Iveco, who design a mirror arm so badly the whole lot swings in, hits and smashes the side window.
And also because the local authorities dont seem to cut the hedges back as they used to every autumn, at least around this area.
I’d suggest pressing the middle pedal and slowing down a bit. I’ve done plenty of tight country lanes and find it works quite well.
When I did the milk collections from farms, the best bit of advice I got was “when running in narrow roads dig the drivers side mirror harder into the hedge than the nearside one, that way when it folds back you don’t have to stop to fold it back out”.
Saved me a lot of stops

My Stralis mirror arm flips back at a touch, and the mirror smacks into the side window. This happens at barely a walking pace let alone at speed, Lanes are all I drive, If I go any slower I would go backwards!
deja vue, I have written this before!

You obviously haven’t done some of my regular drops, where one or both mirrors folding in is a regular occurrence. BTW, what truck do you drive with the pedal-operated mirror arm lock? 
As to Toby’s original observation; it’s quite common on upmarket cars, I can only surmise that the size of electric motor needed to move a truck mirror arm inhibits the use of the technology.
Schrodinger’s Cat, good tip but only if you’re sure there isn’t an old milk step in the hedge. Volvo FM side repeaters don’t like hedges either, don’t take a lot to either rip them off completely or at the least pop the bulb holder out, which inevitably means a new bulb.

-i did this with a two day old motor .a 7.5 ton euro cargo when they first came out-a car came round a bend a little bit on my side of the road,i moved right over with n/s mirror in the hedge,smash!! side window all over my mate-not very pleasant at all!!very obvious design fault.a little while later they came with much narrower arms on the tipper versions
I had this happen today but i was in a van so the mirror folded in but the large mirror glass fell clean out 
was only thick folage nothing solid and no other damage. Had a look on the way back but was no sign of the mirror, thinking it must have already been loose to have come out so easily. Was weird driving it back with no nearside mirror, bit sketchy doing a blindside reverse aswell, thankfully was last drop of the day.
It’s amazing, the number of people who think you’re committing criminal damage/had an accident because your lorry broke some branches on their beloved hedge/tree that encroaches the public highway. Even better when they ask you to tip under the tree but “don’t hit the branches!”
There were some trees on the perimeter of Raf Brize Norton that had “tree protection” orders on them. They survived the Luftwaffe bombing the base but can’t cope with a JCB nearby.
High time a lot of the roadside vegetation is cut back at least a foot from the edge of the road
In fact isnt it the duty of the land owner to do as such ? keep the vegetation form growing into the public highway ?
I will try and get a photo ( next time I go that way) of one place I know where there is a 30 speed limit sign buried approx six feet in the over growing roadside vegetation
I have mirrors broken by other passing trucks and they have driven off, but looking back they could not have stopped to find a place to swap details, as there was no room to do that.
I had a mirror knocked off by a container driver in an area where you could turn a Aussie roadtrain round then said oh it’s only a tipper and give me moody details. Hilarious when I saw him on the a12 a month later and ran him off the road and down the slip straight in to the Olympic stadium.
A228 Colts hill is good for busting mirrors. Every artic and his dog seems to go that way, when the alternative A26 Vale Rise past RM RN is a lot easier and clearer. 
A37 Bristol to Shepton Mallet is well known mirror bashers, there are a few small and narrow villages, and one has a wall that looks like it is about to fall down, as it pokes out a bit, with not much room for two trucks, the cars never give way to trucks going up the steep hill there.

They do when I go up there

Don’t they say that a broken mirror = 10 years bad luck? No wonder us truckers are all doomed! And to those who think its all tight country lanes that do the damage, what about the regional roads where you have to proceed with some degree of momentum. That’s where you meet that car that won’t keep over and that’s where the mirror goes for a crap, never mind the thick limb of a tree up high that’s ready to take your air kit off or make a convertible out of your space cab. He without sin and all that!
What I don’t like is where the farmer comes along and cuts the trees / shrubs back at the bottom to a height of about 4 - 5ft. Makes the road nice and wide for cars, but for larger vehicles that could do with a bit of width! - It used to be the highways authority, or local council that was responsible for cutting back trees and vegetation, but a number of years ago now, the responsibility was transferred to land owners.

And leaves thorns and splinters to give cyclists punctures, and general mess to make the road slippery.
