Suggestion: use real video as the background rather than animated simulated world video.

It is so much better to ride a workout with real video and real views than with animated views.

I believe that Rouvy has this feature now. Wahoo integrates real videos into their workouts also.

Also please look at Mike Cotty Col Collective http://mikecotty.co.uk/the-col-collective/ for examples of videos that are inspiring. Combining this with sructured workouts is awesome.
