Yup, he did the same with Cali HSR. Even most current day negative statements about it are just parroted about things he said years ago. "It's too expensive", "it is going over it's timelines", "no one will use it".

Which, newsflash to people saying that, all major infrastructure projects have that said about them. Look at the Chunnel now, or most suspension bridges and tunnels in the US. They always go over budget, they are always delayed, only some people think they're useful, but after they're built people think "how did we ever live without this?"

Facts are that Elon owns a car company, so he'll say anything negative about any project that isn't going to put more cars on the road. HSR, Vegas subways, BART, he just wants us to buy more Tesla's at the expense of our own convenience and deserved infrastructure
