I’ll leave Carryfast to misunderstand the concept of 3D versus 2D, and flog that bag to death…
Which part have I misunderstood.Mirror and two eyes and brain = 3D.
TV camera and screen and two eyes and brain = 2D.
How do you place position and approach speed of traffic in 2D.It’s not rocket science.

I think (though one can never be too sure regarding anything cf posts) what he is actually getting at is nothing to do with 2d or 3d but more to do with “dynamic viewing”… Let me explain…
With a mirror if you looked at what it’s reflecting without moving either your body or your head you are looking at a static reflection/image, however once you move either left, right, forward or backwards that reflection/image dynamically moves/changes also .
With a screen/monitor though it doesn’t matter how you look at it it will only portray what the camera relays to it and unless you physically interact via a button or touchscreen press will remain constant.
Agree…also, if you are long sighted, do you need to stick your reading gigs on, every time you need to see what’s behind?
This is also a concern of mine being exactly that, I can read a road sign or number plate at a mind boggling distance and have always (so far) passed every medical eye chart test, but stick me in front of a book, a phone screen or computer monitor and I’m instantly transformed into Mr Magoo.
Edit to add:
I can see crystal clear with regular mirrors in any given light or weather situation too btw.

No it’s deffo an issue of 2d v 3d.It wouldn’t even be possible to make a 3d camera system which works over the range required and which is provided by a mirror, a brain and two eyes. [Random ramblings removed]
A mirror is a flat 2D surface reflecting a 3D world, a monitor is also a flat 2D surface portraying a 3D world albeit via a camera image and not a reflection, I thought for a minute you were trying to communicate (badly) what I elaborated on earlier but I should’ve known better and should have guessed you couldn’t be anything other than 100% correct and 100% immovable in your own opinion… My bad.

Just read the links I didn’t write them page 5 of the latter tells you all you need to know.Good luck with ordering an infinite range 3D camera system.

Nice avoiding of the question. What’s the most recent auto box you’ve driven that you base your opinions on Carry?
I’ve never driven a full auto box in a truck in my life.
What auto box would I have needed to drive to know that the thing is blind it can’t see what’s ahead of it so it obviously can’t predict what gear it needs to be in anywhere at any time.
So why couldn’t they rig it with a camera system in that regard.Here’s a clue for the same reason that cameras are no good for determining what’s happening behind and at the sides of the truck.
Oh wow, that’s unlike you to spout off endlessly about something you have no experience of
I drive a Scania and the auto box is a pleasure to use. It’s very rare I need to interact with it. If you put your foot down and you’re in to high a gear it changes down fairly quickly and away you go. If you can predict in advance you’re going to need to change down then you can do this manually with a quick down tap on the right hand stalk.
What’s so difficult about that. You can keep your old manual gearboxes, with proper control of the throttle in advance your can almost always be in the right gear anyway. It’s amazing how these old boys who profess mastery levels of skill on eaton twin splitters etc cannot master a simple auto box.

I’ve used most manual boxes, but there’s no way in hell I’d go back to them.
Give me the ease of an auto box any day…nothing to prove/anything for a quiet life.
If I were still driving I would not miss the massive blind spots that many mirror setups produce (Mercs the worst) plus the trend nowadays to put those big plastic shield on them to make matters even worse.
They are the future and will be fitted to the vast bulk of lorry’s in the near future should you like it or not.
Easy to clean (if not self cleaning ?) easy to set up & no doubt remember your setting at the touch of a button.
If the nearside screen is set just to the drivers left and down a touch (on the dash) then a simple glance with your eyes will give you the info you need while still seeing ahead.
Allin my opinion of course as I used to bemoan most until the FL10 arrived where the mirrors could be set real low and you could see right over the top of them.

You’re normally the epitome of calm, level headed and resonable Luke, but I think I’ve discovered your secret! Carryfast is actually like Kryptonite to you!

Probably, we’ve had the odd run in in the past! I sort of admire how he doesn’t let the fact he has no real life experience of something get in the way of having strong opinions though, though it does make it a bit like shooting fish in a barrel

Which part have I misunderstood.Mirror and two eyes and brain = 3D.
TV camera and screen and two eyes and brain = 2D.
How do you place position and approach speed of traffic in 2D.It’s not rocket science.
If it’s any consolation, I understand exactly what you mean.
A mirror is capable of conveying depth perception, because the eyes look through the mirror at slight offsets just as they do when they look at objects directly. Another way of saying it is that mirrors are compatible with human stereoscopic vision.
A camera and screen is not capable of reproducing that depth perception. It is, at its very best, the equivalent of looking through a mirror with just one eye.
druncle:

Depending on what degree of accomodation remains in the eye, you could well find it impossible to properly focus on the mirrors - although by the same token, your dashboard and dials would have to be somewhat blurry already.
It could certainly impose an additional burden upon the eye, and momentary delays, to move regularly between different depths of focus.

Blimey I thought it was just me.
The mirror is just reflecting the image that we’d be looking at anyway.
To even get close to that you’ll need a stereoscopic camera system coupled to a 3D capable TV monitor screen of the type that doesn’t need 3d glasses.
Sort of useful when you need to accurately assess a gap or place fast moving approaching traffic when making a lane change on a motorway for example.
I’ve not used a truck with cameras but would be interested in trying it.
My thinking is getting rid of the horrendous blind spots like ‘my’ MAN has got, especially the drivers side which can hide whole trucks at roundabouts can only be a good thing.
However, I’ve read most of the posts and 2 other things brought up would be of concern. One is not being able to move closer and side to side to see a different view like you can in mirrors and the other is for people like me that need reading specs. My eyes are perfectly good from about a meter onwards but as I age my near vision is gradually getting worse. So without readers would the drivers side screen be blurred? I guess so.
As for the looks of them…very strange. I saw a narrow cabbed rigid yesterday with cameras, it looked like a person looks with no arms [emoji23]
Used one in the yard to move a trailer…■■■■ wierd.
Kept wanting to look outside the window rather than inside the cab for the monitor,.and found the distance harder to judge…maybe just me eh?
Maybe I’m the wrong guy to give an opinion as I’m a big believer in …‘If it ain’t broke why fix it’ and hate change purely for change sake, but after my very brief and short experience of a one, my words as I jumped out of the cab were …
‘‘You can stick your mirror less Merc up yer arse’’
