Realistically, for a VR headset to be successful it would need to be as light as a baseball cap and have a ~12h power source that would not cause overheating of the wearer's head.
AppleVision is going nowhere. Apple is a mass market manufacturer of status products with a limited lifespan and support. When they work and are supported they generally offer great experience for the money. Apple Car and AppleVision are not such products, but evolutionary dead ends in Apple's history, just like Newton or Apple Network Server. Apple is investing money into an old personal transportation platform when the future of transportation will be based on something else and that "something else" will emerge out of new ideas for urban planning. Some of the tech developed for those products may make its way into those new modes of transport, but it will take a while and may lesser impact than we think.
