VR -A reality check?

Within the large spectrum of possible VR application areas, automotive applications were among the first to appear, and are among the most demanding. Technology has not been sufficiently sophisticated for many tasks. The troubling thought is that we are happy to push the technology envelope, but don't really know how useful this technology is, or can be. Could I do my job even if I had a real-time, ortho-stereoscopic, head-tracked, multi-viewer, wide-field-of-view, high-dynamic-range display with eye-limiting acuity?
