I am confused myself... A short time period in the late 1800 in some secluded European momarchy perhaps, somewhat disconnected from the rest of the world and before all the madness of the 20th century began to unfold...

There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened.

You do own a decent image editing program though, as it seems... 😆

Interesting... All my cars up to now (mostly German brands) had the direct connection between negative battery terminal and chassis.
But as already said, newest car is already 15 years old, so might have changed by now...

The topic of contact resistance is a separate one, would show as voltage drops during heavy load situations. Similar to high internal battery impedance during winter especially for an older battery, when all the lights go out when starting the engine. This is mainly due to the high start current drawn by the Diesel engine (Diesel engines also being uncommon in the U.S. afaik?), so the electronics are designed to cope with this severe voltage drops.

Well, by 2010 that would be a Volkswagen though wouldn’t it?
Yes, has one of the infamous engines that came with the fraud motor control...

But comparing it to modern cars... Crazy what has changed in the time since then...
E.g. we had a water bottle crashing against the main display some years ago, since then it only shows colored smears.
Only downside is, that you now don't know any more, which radio station is currently playing.
In a new car, you probably wouldn't even be able to control AC and heating any more.

I guess I will try to cling to that car as long as possible,..

I don't think so.
The negative terminal of the battery just has a single 30cm long line directly connecting it to the car chassis.
And if that is "floating", the main current source is disconnected and the whole car is completely without power.
So, sorry to have to disappoint you, but that's not it.

That's one of the concerning parts:
It's a 15 year old Škoda, probably one of the cars depending on the fewest lines of code by now...

Das stimmt, allerdings ist es auch keine faire Lösung, die anderen Kinder in der Schule als Hilfs-Sprachlehrer einzusetzen.
Ab dem Schuleintritt haben die nämlich selbst schon genug eigene Herausforderungen, gerade in Bayern (ich sach mal: Grundschulabitur).

Die Sache ist schlicht, dass der Zeitpunkt bei Schulbeginn viel zu spät ist.
Gemischte Kindergartengruppen sind eine tolle Sache für alle Seiten, und Kinder lernen da ratz-fatz die Sprache, habe ich selbst mehrfach bei uns erlebt. Dafür müssen die Angebote erstens existieren, und zweitens die Kinder da auch hingehen. Das selbe gilt für Horte und Nachmittagsbetreuung nach der Schule.

oder wenn im häuslichen Umfeld nicht Deutsch gesprochen wird.

Herrschaftszaggrament, vor dem Hintergrund ist die Quote ja erstaunlich niedrig für Bayern, des sog da i!

Or: a software glitch in need of a hard reset.
Most electronics have a lot of capacitors to stabilize the input voltage.
When the device is in some low power state, it can take a surprisingly long time until these run out of their charge after disconnecting external power.

We recently even had that for our car.
ABS stopped working, along with other things like remote car opening and also the turn signals for some reason (rest of lights still worked)
Repair shop didn't find any errors in the electronic log, but on a wimp disconnected the battery and let it sit there for a while.
All just worked normally again after that.

While this is typical software glitch behaviour, it is slightly disturbing in a car, especially involving safety relevant functions like ABS and ESP...
