So you test the system with human drivers for a few miles, and if none of them dies then it's secure ? You actually rely on the subjectivity of uninformed users to assess the reliabilty of a safety-critical system ?
>> Not really. It's mostly subjective.
No. The quality of a safety-critical system is not subjective.
>> I think most would generally agree with the quality assessment.
You are not qualified to make that claim, and neither are your users.
