First day/night with the M3 yesterday.
No, the camera is not HD-sharp like the MS. However, it's solidly decent and the backup lines are exceedingly accurate when parking.
Only problematic issue is the image darkness. Presumably one of the many early-days software/calibration issues which will be fixed.
Our DS specifically mentioned that Tesla wanted to roll out to experienced Tesla owners after employees and before general public so we could start with a basis of Tesla understanding, be able to handle v1.0 issues, and provide feedback to enable their rapid resolution.
