Sure, there are commercial applications like DtG mentions. But that's the point. The only people using VR technology are city planners, automotive designers, pilots, military personnel etc. The technology hasn't trickled down to you and me.

What's ironic, to me, is that a friend was telling me of having a couple of VR developers demonstrate their system to his high school science classes so many years ago that they ran it on a Commodore computer (remember them?). The hardware has gotten a zillion times better, so it's gotta be easier to do VR technology than it was back then, but it's still only available to a very specialized few.
