Do you have ultrasonic parking sensors? If not welcome to the wonderful world of Tesla vision where you lose features you paid for and Tesla basically tells you to go F yourself for asking for them back. Because "Elon" said it'll be better two years ago means in reality it'll never happen. You know why? Because he's pissing away time and money at Twitter. He's there because he couldn't control his big mouth. Any second now queue the fanboys leaping to the defense of a billionaire that'd throw them on the street in a heartbeat if he thought it'd make his share price creep up by another couple of precent.
