This is hard (impossible?) to see from inside the moving vehicle (and I keep forgetting, on the very rare occasions that I team drive with another car, to ask the other drive to look at it), so I've never been able to see if for myself;

I wonder -

When Adaptive Cruise Control slows the car to avoid getting too close to a slower car in front, does it turn on the brake lights? I think it should, at least if the ACC slows the car more than extremely gently/ especially if ACC slows the car somewhat abruptly or very abruptly because some idiot has pulled into the lane in front going noticeably slower.

My car happens to be a 2019 model year (mfr Apr 2020) Octavia Scout (2.0L diesel, DSG-7), for what it's worth.

thanks,

according to the hand book (for the Superb although I would have thought the Octavia is the same) the answer is yes & no

Thanks for that - sorry, I try very hard never to ask questions that can be answered by R'ing TFM (and I have R'd TFM) but apparently the long-COVID brain fog is really getting me sometimes these days 😞

Okay, so, it *should* do the right thing... (I still want to test it; I wonder if there are magnetic stick-on mirrors that will hold up to 100km/hr+ speeds at least long enough to see my own brake lights? 😸).

Back when I lived in the US, that would have been an everyday opportunity. But ever since I moved to Spain (sixteen years ago now) I don't drive much, and I essentially never team drive with another vehicle.

Interesting how our habits can change. Actually, thinkging about it, this coming Monday I might have the opportunity.

 

I still kind of like the idea of a 1950s-era SciFi-looking think-Martian-bendy-neck chrome mirror magetically stuck to the side of the car to let me look at my own *ss 😁

Has anyone tried seeing iif ACC works when you're in reverse after all its doesn't explicitly say " do not use in reverse" ;o)

Since ACC relies on the forward facing radar it would need to see through the car to work in reverse...

OOOOorrrrrr, it would have to see allll the way around the world until it catches up with itself from behind!

Or would it work but at a fixed speed ;o)

I spent a lot of my life working either in software engineering or information security. In any product or process, there's the obvious "what it IS supposed to do" (functional requirements), and the less-obvious "what it's NOT supposed to do" (non-functional requirements). I _hope_ that in automotive engineering they think of those things (mostly, experience suggests that they do - they default for the assistive systems [when they're seeing ghosts and shrieking that the car is about to collide with something that isn't there 🙄] is to turn off and return full control to the human driver whenever any parameter is outside of the defined operational range)...

But, hey, if I can magnet-stick a mirror on the *ss of my car to check out the brake lights when the (forward!) ACC has to slow down hard, I suppose someone else could re-aim the ACC sensor backwards into the engine compartment just to see what it would do 😁

It would perform like the place name used by Dylan Thomas , Llareggub (read that place name backwards).
