Proposed compressed-air thrust for the Tesla Roadster faces engineering criticism

A commenter argues that delivering extreme thrust with compressed air in a production Tesla Roadster would require major compromises in weight and storage, with only seconds of thrust before specialist recharging. They also criticize how those capabilities are marketed and say deposits are being taken based on what has been shown. The commenter says Yann LeCun made similar observations; LeCun later reposted the comment.
