This news is months old. Honestly agree with musk on this one. We are able to drive with 2(sometimes only 1)low resolution(sometimes out of focus, sometimes closed) cameras on a pivot inside the vehicle with further blindspots all around. Much of our rear situational awareness comes from 2/3 small warped mirrors strategically placed to enhance those 2 low resolution cameras on a pivot. Tesla has already reverted to add some radar back in... The lidar option sounds like dystopia waiting to happen (just imagine all streets filled with aftermarket invisible lasers from 3rd world counties, any one of them could blind you under unlucky circumstances). The best way forward is visual, and if you watch up to date test drives on YouTube you can see they are doing quite well with what they have.
