Mostly the latter, in my experience. Germany has dynamic signage on several highways, but if the sign says 80 (even with a secondary sign notifying of traffic jams), most people will still drive 160 if it doesn't look congested yet.

That’s simply not true. Most people don’t even drive 160kph to begin with.
In some parts of the highway is very plausible. Even 200km/hour and more
People seem to have some terrible difficulty of understanding the difference b/w “Most people don’t do <x>”, and “It’s theoretically possible to do <x>”.
People seem to have some terrible difficulty ...
All / most / some people? Or just the person you responded to?
There are multiple reason why the way people communicate is important, one of which is the limited logical reasoning capability of most people.
Just look at politics / marketing / dark patterns / mortgage contracts.
I successfully changed my sister's mind from variable rate mortgage to fixed mortgage, as the language of the contract doesn't explicitly write how bad the worst case option can be 10 years from now for variable rate mortgage.
In unrestricted areas, this link says the average speed of cars is in the 140-150kph range, and about 20% of all vehicles above 160kph, so while you're right, it's not as extreme a difference as one may infer from your tone.

That depends on what country you live in. Some areas in Germany, 200 km/h is no problem for hours straight.
I live in Germany. And what you’re saying is (a) wrong, and (b) not even incompatible what I said.
"Some areas in Germany, 200 km/h is no problem for hours straight."
Please tell me of one road/route in Germany where you can drive '200 km/h for hours straight". I'll settle for tiny values of 'hours', as long as they're >= 1.
This ofcourse depends on time of day. An early morning somewhere around 2 am - 5 em we were driving from Sweden down to south-west germany, somewhere after Hamburg. We have a small car, top speed is about 200 km/h in downhill, wind in the back. I had the gas pedal to the bottom for several hours, most of the time it was four lanes and the only thing you saw was a truck every few kilometers. This was a few years ago so not certain if this has changed. Last time we drove down we ended up on the wrong highway and stuck behind a heavy transport for the same ammount of hours doing 70 km/h tops, when we weren't standing still. Friends told me the heavy transports blocking the whole roads have gotten a lot worse in the nights, the last years.
From experience this is rare. 20kph above the limit is standard (and probably expected by the system setting speed limits), 80 over would cost your license for several months.
Admittedly, 160 was exaggerated. But on stretches where there's no speed limit and you suddenly get this 80 km/h along with Stau signs, people tend to still drive 120 if there's no visible congestion. Since those dynamic limits are not really enforced (most speed cameras tend to be in places where there's a fixed limit at all times) there's rarely a downside to drivers. Same as with driving 80 in construction sites instead of the 60 that's signed.
This is starting to change now that the polizei have started leaving mobile panzerblitzers in place for several days at a time. I've noticed in the last few months significantly more respect for changes in speed limits from the folks with local license plates.

The ones still driving 160 are mostly foreign drivers in my experience. Most German drivers obey the speed limits. Note I'm not German but often drive through it.
As somebody who was using the Autobahn quite a lot I’d say most people go between 120 and 160 when there is no speed limit. But it depend on the conditions
Admittedly, the 160 was exaggerated. But as a German who does obey the speed limit, my experience seems to be that most drivers don't.
