I'm fearing the day when my quite old ICE car dies and I end up in a situation where the best option is a newer car that is a computer on wheels running software that I know will stop getting updates very quickly. Of all the new cars ideas I've seen recently, only the Slate mini-truck seems to be taking a minimalist approach, with no fancy head unit or navigation system.

Consider an electric cargo bike if you're life will suite it.

I'm starting to think the short software support isn't a bug, it's a feature. They want the car to feel obsolete in 5 years so you're pushed into buying the next model. It's the smartphone sales model, but for a $50,000 purchase.

Planned obsolescence

Planned Obsolescence 2.0 - they can tell the system when it's time to die.

If they had just clipped the antenna wires, how likely would that have disabled all outbound communication? Clearly not as good as disconnecting the modem (which removed some software checks), but more approachable without the multi hour disassembly.

You generally have to disassemble far more annoying things to get to the antenna than to remove the head unit.

A better way might be to install dummy loads on the antenna outputs.

There's no way they're going to keep a modular car functioning for years without relying on frequent software updates.

Same, early 2010s IMO seems to be the point where the industry really started to shift. There are some good cars from before this time, but keep them running past the 2030s will be a challenge.

If it's a pre-computer car, all you need is a machine shop or access to one.

Nice work. I'm honestly surprised that the head unit didn't complain about the missing modem. Although it's far from returning to a simpler less software heavy car, removing the cellular connectivity is a promising start that surely hugely reduces the attack surface of the vehicle

If you install fully shielded resistors it can work, but shorting the antenna completely will have the added benefit of destroying the RF amplifier transistors. From then on the car will just think it’s out of cell range, and there’s not much chance of leaky signal. It’s not too hard to make shielded loads though.

I do prefer the option of removing the entire cellular module though.

Any non-disable-able connectivity will be an absolute deal breaker for me on any vehicle I own. I guess that probably means I’ll be buying used vehicles for the rest of my life, but it is what it is.

Did it for 100 years. Nkthing changed. They don't need to make cars into surveillance systems. That's a choice.
