I have a van which does not have the rear view mirror. Yes the door mirrors are excellent but you are always mindful of what you can't see (particularly pedestrians when reversing) and cautious as a result.
So no way would I delete my rear view mirror.
But in the Morgan, you can look over your shoulder to check for pedestrians or indeed anything else when reversing.
When I was taught to drive, almost 50 years ago, I was always told to reverse by looking over the shoulder. IIRC it was a test fail to reverse only using the mirrors.
