There is a general rule on bugs is that the more devices they are on, the more apt they are to trigger.

A CAN with 10,000 machines total and relatively fixed applications is either going to trigger the bug right off the bat and then work around it, or trigger the bug so rarely it won't be recognized as a kernel issue.

General purpose systems running millions and millions of units with different workloads are an evolutionary breeding ground for finding bugs and exploits.
