So that explains your lack of knowledge re your assumptions about the cars. Do you think it's possible you might not also fully understand the testing program?
Ugh. I truly hate to play this 'well I'm this in my career' game, but it seems important to you. I'm a software engineer by training, have run a fairly large multi-displinary engineering organization, designing software-driven complex electro-mechanical critical systems. I ran quality and regulatory for a Fortune 100 company, which included software verification & validation teams and final design validation teams for Class II and Class III medical devices. That's not even touching on the regulatory functions I oversaw. I also paid for my own education, going back with a baby on my hip after walking out of a bad situation. I've supplied training to FDA investigators, teaching them how to properly evaluate V&V planning and results. I do know a little something about this field. Okay now?
Tesla's validation system / safety testing do not put people in danger, unless (like with any product) they believe they know better than the company. If I didn't believe that, I wouldn't own the car. And I sure wouldn't drive people around that I care about if I believed that.
I've interacted with the company for 7+ years. I have zero worries. You do not have any knowledge of what Tesla does, except what you find on social media. And that is not a source.
You're a software engineer ---- I do life safety systems for manufacturers (LONworks, Modbus+, BACnet)
I don't want to over generalize --- but the criticism of Tesla is that they approach their problems from a Silicon Valley approach as opposed to a real world approach
