When passing another rider, or when being passed, one bike will often animate in annoying jumps. It looks like one rider is hitting the other with his shoulder.
I have seen it much worse - to the point where rather than draft with another rider, I have stopped pedaling to let the other rider get away just to get the immersion-breaking animation to stop. I also don’t want to ruin some other zwifter’s workout just because we’re riding at the same speed.
And that is just one of the reasons I ask other Zwifters to please not draft off of me. Most respect my request (9 out of 10) the others are not as nice.
If they don’t reply, I figure they have chat turned off or something else. I can drop them by dropping back a little and letting my HR go to the bottom of the zone I am training in and then pass them. They usually get the idea.
The 10% I am referring to make harassing comments and even worse. I don’t understand why they can not respect other Zwifters requests.
I believe that jitter is caused by being on the edge of breaking out of the sticky draft. It is a good indicator for the following rider to back off the power a little to stay in the draft.
People who don’t like other riders around them can try disconnecting their internet connection after starting the game and reconnecting at the end. You’ll have the whole world to yourself and nobody to annoy you in between.
