Because it can be trivially duplicated, this is minimally capable engineering. Yet automakers everywhere lack even this level of competence. By reasonable measure, they are poor at their job.

Compare this to the databus that is used in today's cars, it really isn't even a fair comparison on cost (you don't have to have 100 wires running through different places in your car, just one bus to 100 things and signal is separated from power).
I don't really want to get into a big debate about this as I haven't worked on Jags, but I don't believe that replacing parts of the loom is would be that expensive. Remaking an entire loom, I will admit that would expensive as that would be a custom job with a lot of labour.

Ok fine. But the discussion was button vs touch screens and there is nothing preventing buttons being used with the newer databus design. I am pretty sure older BMWs, Mercs etc worked this way.
In any event. I've never heard a good explanation of why I need all of this to turn the lights on or off in a car, when much simpler systems worked perfectly fine.
Reducing the copper content of cars and reducing the size of the wiring bundles that have to pass through grommets to doors, in body channels, etc. was the main driver. Offering greater interconnectedness and (eventually) reliability was a nice side effect.
It used to be a pain in the ass to get the parking lights to flash some kind of feedback for remote locking, remote start, etc. Now, it’s two signals on the CAN bus.

I am not sure about that. You still suffer from electronic problems due to corrosion around the plugs, duff sockets and dodgy earths as the vehicle ages.
