It's not about optimism. It is well established in the industry that Tesla's hardware-stack gives them 98% accuracy at the very most. But those voices are drowned by the marketing bravado.
In the case of Musk it has worked out. His lies have earned him a fortune and now he asks Tesla to pay him out with a casual 1 trillion paycheck.
To correctly assess the state of the world. Since Tesla exclusively uses visual sensors, they are massively limited in how accurate it can ever be… or safe.
‘Correctly’, like ‘accurately’ is with respect to some measure of correctness or accuracy. I’m not being merely pedantic here. A sea anemone assesses the state of the world just fine, but not with respect to driving.
Humans use mainly vision to drive, and what isn’t vision is also accessible for robots; mainly accelerations and sound.
So it doesn’t mean much to say that Tesla can’t be ‘accurate’ without describing what you want it to measure. What exactly to measure, and how well you need to do it is deep and key question for the technology.
