Tagging on the back of pros when they're doing any kind of efforts or interval blocks is an absolute no-no..
If they're just rolling easy/ doing Z2 it's a bit different but if you're gonna sit on for more than a couple minutes it's probably best to ask if they're alright with you tagging on the back for a while.
Anyone who actually trains knows how irritating it can be when you're pushing hard. Even if you're not pushing, for someone like Jonas who is a bit on the spectrum/hypersensitive it's gonna be really annoying if someone you don't know won't get off your wheel.
If the guy cannnot read Jonas body language to see that he's not wanted there then he's clearly lacking a bit of social intelligence.

Just guessing the thing that got Vingo upset, crashing and angry: When riding hard and fast with others, you're not only focusing others on your side and front of you.
You are also just a bit tense of possible sudden group braking situations and someone crashing on your back wheel, on your arms, legs, whatever causing sometimes visit to ER. Can get you pretty tense, sometimes more, sometimes less.
Probably less with fellow pros who know all these nuances and case adapt. Probably loads more if someone unknown gets glued to you and you suddenly wonder if there's a risk, lets say this unknown does not brake that late and hard as you do and btw is just focused fiddling his camera or whatever.
And as all this **** creeps inside your head in the middle of some WT pro level hard interval (lightspeed for many of us) you just might make mistake yourself. A fatal one actually in those speeds. Heck, one look too much and it's case Egan Bernal pretty quickly.
