There is certainly some truth that "some company" overpromised and underdelivered. They advertise "full self driving" but then hide in the fine-print that "oh jk, not really, but its still full self driving if anyone asks ;) ;) ;)"
I think the frustration stems from the obvious falsehoods in the advertising, and the doubling-down on the tech, despite the well-documented weaknesses of the implementation.
Have you driven in Tesla FSD recently? If anything it’s undersold. It’s an absolute miracle. I use it everyday.
Please be courteous to other drivers on the road, we all share it. Just make sure you’re the one in charge, not the software. This isn’t to put your argument down, but to offer the perspective of people involved in accidents. Loss of life is bad, but surviving accidents is also equally bad.
