I don't think VR is ever going to reach that point, just because our eyes are too important. Very few people would be comfortable putting a VR headset on while commuting on a subway or bus - because you lose all awareness of your surroundings. With sound you are losing one sense, with VR you are losing two.
AR is the only one with a hope of becoming socially acceptable in public, but it will have its own hurdles (Namely the fact that you will always be pointing a camera at someone just by looking around.)
Buses and trains absolutely, missing your stop because you're too engaged in something is a real possibility.
That same ability to transport you to some other world was an absolute godsend on a recent 12+ hour flight from SFO to Beijing. My Oculus Go has been added to my list of long haul flight must haves in addition to my QC IIs.
FWIW you cant see the haters staring when you've got it on LOL.
