Ok, but their engine controller was found to have 12,000 global variables and no one could ever say conclusively that the pedal issue was real or not. The issue was not that no one found the flaw, it’s that no one could prove it wasn’t there.

    Yes. In fact I would trust such a system far more since a more procedural approach to the system would be much, much easier to spot bugs.

      My man. As someone who works on Autosar controllers, your trust is extremely misplaced.

Are cars since then required to have formally verified codebases, or is "no one could prove [there are no bugs]" still true? --- Trying to evaluate what happened based on observation of events alone and stats, in absence of a formal proof of issue or non-issue... the cars didn't just disappear overnight so if there was such an issue... where did it go?

  That software was never fixed. Those cars were still on the road after the "scandal". The problem went away somehow.

    This isn’t true. Toyota issued multiple engine controller updates. All mfgs do, all the time. There are no changelogs. It would also matter what their typical car lifecycle is, it could have been just before refresh so only effected a couple years. It could have also been bad floor mats. We’ll never know - but the point is, that their code was so bad you COULD never know.

      They also never caught the clowns in the forest stealing children, nor the satanic groups sacrificing babies in the 80's.

I'm suspicious that a lot of those 12,000 are constants. Just based on how I think those guys operate. You and I would change a constant and recompile. They will just splat location 0x239A
