I don’t know about Tesla but I know that Elon Musk is very careful to qualify all of his obscenely optimistic timelines with “I think that…” or something to the same effect. Most likely to shield himself from lawsuits. He was saying Tesla cars would be a self driving fleet back in like 2018. He was saying autonomous Teslas would be printing their owners money. Somehow investors don’t give a shit that he just keeps making up bollocks then never delivers.
