The idea is there.. but the graphical aspect will require a lot of investment to get the quality to the standard an end user would expect, more so with the likes of the new generation consoles hitting the market. ie PS4.
The end result of this product is just a basic video in my opinion from a gpx file or simlair, its not like you are covering your body with data sensors to monitor your positioning and weak spots like pro roadies do.
Good luck but im out. (my opinion rather than factual. )
