As with many of its ilk, the Infiniti EX Concept has dramatic, swooping sheetmetal that’s quite attractive and modern, yet also impractical in terms of rear head room and visibility. While the Around View Monitor (AVM) will certainly help with visibility, it’s also nice to be able to look around for yourself without the aid of cameras. One thing the concept has that we wish the production version would get, but know that it won’t, is the liquid crystal full-length glass roof panel that changes from transparent to translucent via input from a special touch sensor system.
