He was saying several years ago that he would be start building a Mars base in 2022 and have manned missions in 2024 which are both basically no closer today than they were then, that was a lie.
He said he would build hyperloops that would be cheap fast efficient across the country, that was a lie, that we now know was to stop building public transport.
He said in 2016 that full self driving that was safer than a person driving would be ready in 2017, and that was something they could do TODAY (in 2016). He repeated that lie in 2019, even claiming people could make up to $200000 per year if they bought a Tesla, because they could drive as autonomous taxi's beginning 2020. He claimed buying anything other than a Tesla would be stupid, because Tesla cars were the only ones that could do that. Except they couldn't and they still can't.
There is a very clear picture that Elon Musk is lying through his teeth, and he cons people into investing in and buying his products under false pretenses.
