Great to see that ghost riders are coming! One of the most requested features - Personal Best Bot (the “83” votes are misleading - there were nearly 800 before it got messed up).
Q: Can I ride against other Zwifters’ replay?
A: Not at the moment! For now, you’re only able to ride against your own segment data with hologram.
It’s good to read that this appears to be something planned for the future. \o/
