I find it extremely annoying, most rides for me are free rides I pace miles and elevation and it messes up the dash so I can’t see where I am at so I can pace myself. Zwift needs to make pacer rides, pacer rides. It shouldn’t interfere with a ride or exercise someone is doing as it messes with peoples concentration and confidence as they focus on their ride. Just my two cents. Never seen it change my route but if they start when I’m riding by, I’ve kept pace for over 40 minutes and it ruined my numbers because I had to slow down and wait for it to get ahead.
Like in real life…there are cycling groups that overtake.
Turn off your Wifi, ie disconnect from internet, and you can Zwift in your chosen world all alone.
When you want to stop and save ,or want to change worlds etc, you must reconnect to save.
I don’t know if you need to reconnect to change routes or start a work out but I would just to be safe.
Get it set up the way you want and disconnect and then there will be no distractions.
