Not even remotely the same thing. You completely glossed over me saying potentially broken software and heavily populated. Surely there is a way to simulate a left turn signal in a more safe manner on software this early in the testing process.
It's not surprising that it made a mistake during testing. That's what testing is for: rooting out mistakes.
Testing is for rooting out errors. Validation is for proving you achieve the desired specifications and failure rate. Validation occurs when you believe you are done or when testing becomes inadequate to discover failures. It is about “proving” the negative with respect to errors.
Broken, incomplete software where defects can be routinely discovered after light usage has no place being used by consumers on public roads.
