Is this bad behavior from lorry drivers?

In Germany when you are towing a caravan you are limited to 80km/h (50mph). During certain hours lorries are not allowed to overtake. So I often have a 10 mile tailback of lorries. Never seen any bad behaviour from them.

There are exceptions / exemptions depending on the weight of the towing vehicle and the trailer / caravan.
Unless you have a very small car and a very big trailer /caravan the speed limit is quite likely to be 100km/h

https://fr.humbaur.com/en/useful-information/100-kmh-regulation/#:~:text=The maximum speed for a,up to 100 km/h.

To go at 100km/h you have to take a TUV test which costs 70 euros and takes 2 hours. Not worth it for a few weeks. It's the Germans that make the rules so they can't complain.

I think you have been mis-informed there. No test required. Just get a 100kph sticker in addition to having met the vehicle specifications.

You even put a link to a website that states:

The maximum speed in extra-urban areas is 80 km/h. In some situations, however, the relevant traffic authorities may grant a special permit to travel at speeds of up to 100 km/h. If you have been granted this permit, you are permitted to drive your car-trailer combination at speeds of up to 100 km/h on motorways and dual carriageways (but not country roads!), instead of up to 80 km/h. You will need a speed limit sticker to certify that you are permitted to drive at speeds of up to 100 km/h; this can be obtained from your vehicle licensing agency.

To be granted the permit you have to take a TUV test and pay 70 euros. You can then display the 100 sticker. Being granted a permit is different to buying a sticker!

My husband actually got a minor on his motorbike test for going to slow on a dual carriageway, think that was 10mph under the speed limit? 

I also remember arguing with a teacher back in the 90's that lorries had speed limiters and they quite vehemently said that was not true.

It is a black mark on the test for not driving at or close to the speed limit where conditions allow for it, severely under they may even fail you

Maybe at the time they didn't have limiters, now they do

Tyre pressures and load will affect the speedo a small amount but different tyre brands can affect the speedo more than that.

Company had a Toyota that kept throwing up an ABS wheel speed mismatch code. Turned out when they replaced the tyres they
had 3 Michelins and one Uniroyal. A good 12-15mm difference in the overall height of the tyre, enough of an error to throw
the fault code.  (it was a long time ago now so brands maybe incorrect, but the tyres were the same stated size).

Yup, hence the reason for the speedo to be set to over-read so if you do something like that, you won't be speeding if your speedo says you are at the limit

UK Speed Limiter Requirements 

Since 1 August 1992 all-new goods vehicles over 7.5 tonnes maximum gross weight and with a speed capability of over 60mph have had to be fitted with a speed limiter calibrated at 60mph,

Certainly when I took my test (almost 40 years ago now!) I was told by the instructor that most of the test would be round town (30mph limit) but the examiner would take you to a 40mph zone.  If you didn't speed up when you were in the 40mph zone - assuming it was safe to do so - you could be failed.  Makes sense, I suppose - it shows either that you're not confident enough, or even that you hadn't noticed the change in speed limit.

Bit of both but also the test does talk about making due progress

I found the below on a driving school page 

Driving faults recorded
20 Progress

Appropriate speed:

• Crawls along at slow speeds on clear roads.
• Makes no attempt to achieve maximum speeds for the road when safe to do so.
• Reduces speed excessively when the conditions do not merit doing so.
• Makes slow progress through the gears in normal driving.
