Chip shortage continues... From what I understand the shortages are related to the infotainment systems, not critical functions? The off-road cameras are cool, but maybe putting all these gadgets into cars is counter productive.

Vehicles are getting so complicated . I suggest that car makers adopt aviation style electronics where you have a "critical" system data bus and a separate bus for cameras, entertainment and the host of creature features that drive the cost and maintenance up. This would allow for easy and less costly upgrades..the expense of added wiring would be minimal and allow buyers to select those items which are important to them.Chip shortage continues...

I was refering to the open ports for expansion and the isolation of critical systems from basic operating systems. for example: the current tech allows a failure in a mileage enhancement feature to place the vehicle in "recovery mode" which is extremely restrictive. I had a transmission thottle sensor failure on my Dodge which made the vehicle inoperative vs just allowing less efficient shifting and "harder shifts" note that the harder shifts were just what all trannies had several years ago and not damaging in any way.They are segmented.
Different manufacturers split them out a little differently, but the basic concept is this:
There's "CAN-C", the chassis bus. It connects the modules necessary to run the car and some ancillary stuff. Engine, transmission, etc.
There's "CAN-IHS", the internal high-speed bus. It connects the infotainment, comfort, and convenience modules.
There's simple, low-speed one-wire LIN-BUS connections too, for things like steering wheel buttons, seat motors, etc. The LIN will connect back to the rest of the car through a module sitting on one of the CAN busses.
Then there's a "CAN-D" network, the diagnostic bus. That's the one that connects to the DLC (diagnostic link connector) under the dash. Now days that bus communicates only with a security gateway, and that gateway connects to the other busses (sometimes including a dedicated CAN bus for the wireless module).
Yeah that's intentional. If a feature malfunctioning didn't affect the drivability of the vehicle, users would likely just ignore the dead feature and keep using the vehicle like the transportation device it really is. Manufactures want to force you back to their dealer network for every little thing that goes wrong.I was refering to the open ports for expansion and the isolation of critical systems from basic operating systems. for example: the current tech allows a failure in a mileage enhancement feature to place the vehicle in "recovery mode" which is extremely restrictive.

This is the business model that I’m hoping never makes it to vehicles…forcing you to use a dealer for repairs:

That's an expense we shouldn't have to deal with. For enthusiast cars people will spring for it, but most consumer cars are seen as disposable so paying decent money for an aftermarket work around won't be viable. It's just going to push cars into junk yards sooner, raise new car prices, and start to price vehicle ownership out of the middle class.That's where the cottage industry of developing and installing replacement controllers will become very lucrative.
