For me I dislike the isolation and feeling that someone can sneak up on you so my speculation is that it's not a great daily driver but could be useful in spurts. Maybe after a while it would feel normal but I am unsure.
It could have a look-behind mode that swaps around 180 degrees to the rear camera array while you're in reverse. Better spatial awareness than a backup camera on a screen.
I could definitely see homeless people turning to a virtual world to avoid their dreary lives much as they turn to alcohol and drugs now...
I think that is a long way away, though.
