I would like to see some of the AI Ghosts replicating laps set by pros that have used Zwift. For instance have Jens Voigt lay down his fastest lap and then convert it to one of the AI Ghosts so the public can then compete with the Ghost of Jens.
Have the ghost viewable in the join rider section or have separate section with available pro Ghosts. Maybe cycle them each week to have different pro ghosts and make a weekly feature from it.
It’s definitely one that’s been kicked around.
