As mentioned in the article as part of the introduction, there were problems with those car regarding security. Especially with the Rav4 where a colleague, Ken Tindell, showed a very serious flaw: https://kentindell.github.io/2023/04/03/can-injection/

Because of this OEMs build in more and more security, like SecOC with Autosar and other similar things. More and more of those security feature depend certificates in the devices that have an expiration time. Those certificates needs to be rotated regularly. If the rotation does not happen, because of missing communication with the mothership, then the security will fail, which finally will lock you out of your car.

That will be true for all the coming luxury car models.

IRC, Tesla has something like this for years in their cars. They can be offline for a certain period of time. But when this runs out, you will be out of luck.

It offers Word -> PDF conversion. Just for interest I tried it and it doesn't even get the simplest page right. It puts the filename into an header. The test page had 4 images, one svg, one pdf (from svg), and another variation of the first 2. The generated PDF only contains 2 of those images with wrong sizes. The later two are missing. So it's basically completely useless.

The free of charge LibreOffice gives much better results with its own caveats.

Like Hydac moved some of there assembly from China to Germany.

A company in the district nearby, just moved their whole production from Thailand back to here. Yes, production costs are higher. But there is not transportation costs. They don't have long lead times anymore and can react more better to demand. So the overall costs assessment lead to the decision it is better to have production here locally.

I recommend to go to SPS, Agritechnica, and so and talk to actual people.

BTW: Even as Continental has layoff. There are other companies around that happily absorb those people. Because 2 years back, that had problems employing people.

From my knowledge, the last time (2022ish) we talked about that was, that they don't take new customers for now. They are working at capacity.

I just named some big name brands. I also know mid-size and smaller brands.

Building your business and getting your stuff together is hard for any startup in any business field.

Bosch, Continental, Siemens, Palfinger, FAUN, Webasto, Phoenix Contact, Beckhoff, …

> After the 2019 closure of the Puttgarden-Rødby service between Germany and Denmark and the seasonal Sassnitz-Trelleborg route linking Germany and Sweden in 2020, the Intercity is now the last one running. All the rest were replaced by bridges or tunnels, or proved too expensive to maintain as demand fell in favour of air travel.

You can start off just with documentation and then in the process check if the code is still in line with the documentation.

You can also generate documentation from the code. Then check yourself, if it fits.

They also test and publish yearly the latest battery combos.

When you use a µC to make it cheap, then you don't want to use additional components.

The majority of end user devices are run from within private networks protected from the Internet. If you have connected to your cell provider, then in the majority the cell providers are running their own private networks. For one reason the IPv4 address space is limited as such, that there are no other possibilities. IPv4 is still the important protocol compared to IPv6. Second, it is that those providers, want to protect you. Some don't even allow cross communication.

If you devices are connected with Wifi, then there is the very same situation. There is almost no campus, commercial, and home network, that gives you public route-able IP addresses. I only know a view deployments were you get public route-able IP addresses at conferences like C3, EMF, and alike.

tl/dr: No, the end user devices is not easily to reach without additional infrastructure.

Any push service works this way. The client contacts the server to be updated. The server gives a no data or a data response. The server cannot magically contact the client.

Because if you want to move your business later, when it grows, the tax office will regard your home as part of the business. Things will get complicated that way.

I assume that this was also true for other brands.
