Your sense of “disappointment” depends on your own expectations, not GM or Cadillac. There is and never will be a “perfect car”, unless you have the funds and knowledge to build it yourself (which is what Elon Musk did and failed). So you must either accept the offers in the auto marketplace, reject all of them, or lower your expectations. It is now your choice.
If your view of the Lyriq is already “disappointing”, just leave this forum and forget about it. Posting depressing comments for an object that has not been produced yet shows what type of person you really are. If you want a bad car , you will get what you want!
