And my issue with your statements is that you're trying to have it both ways: you're claiming both that "there is no problem" and "Tesla told him about the problem so it's his fault". You have to pick one.
Tesla don't make preconditions on where to use their autopilot. How many Tesla's discover a new 'problematic' strip of road each day? Is every first Tesla to drive down a new road to become a crash-test dummy when it turns out the autopilot just can't handle that next bend in the road?
It's absurd to think so. The product is not fit for purpose. I'm confident the law would agree.
