Even better would be the ability to shift into The Flash mode, and run/bike/ski at super high speeds! Of course, if you're over 50 you have to hum the theme song from The Six Million Dollar Man while you run in slow motion but achieve 60 mph.Google Maps has street view, right? What about a scenic display that you move through at the speed you're pedaling? (or on a treadmill, running?) Maybe even with a programming interface that adjusts resistance to video terrain, so that if you're going up a hill in the video, pedaling gets harder?
You could have video libraries of famous streets, trails, bike races (like doing a section of the Tour de France) and the experience would feel like cycling through the actual locations ..... right down to how fast you're going.
