> Now that was a $two-figure USD device, not a $5/6-figure USD electric SUV. Is this a cost-cutting measure? At those price levels, doubling your NAND size is not even half of a percent of the total cost of the vehicle.
Could just be a competence and priorities problem. If it's cost cutting, it feels way more likely that some PM cut some story from a sprint to hit a deadline (and objections were either not raised or ignored), than they did some engineering analysis and explicitly decided to save $3 per vehicle by cutting the NAND size.
Edit: Actually, I don't think that technique would have helped, the problem wasn't a botched update, but a seriously buggy one. From the OP:

That and combined with general refusal of new automotive bootloaders to downgrade. You can go only up in versioning. So even that you could have working version on second partition, it will never get loaded because it has lower version than currently one you are running.
