Since the beginning, i've only seen them IRL once, because I had to travel from a town to another at the very first day of the protests.
Just took over the whole line of stopped car with a yellow vest on the car and waved at the people blocking the roundabout.
Did not see them since then. I live in a small town ( ~ 150 000 inhabitants ) and I don't drive, I either walk or take the bus/tram, which i've yet to see them block
Also had to take a plane and a train 3 times during the protests, airports weren't blocked, railway stations weren't blocked.
They're invisible to me, ( middle classe, live in town, student ), which kinda makes me think they're blocking what they THINK are strategic places : roundabout and shit.
Except they're just pissing off people from their own world : lower class workers working in town or industrial areas and living in remote locations for cheaper.
I very rarely watch TV too because it's just a pile of garbage, what I feel tho, given news reports on the internet and on media's twitters, is that they really don't cover police violences enough.
They're focusing on the protesters violence, even though during every protests there is violence, no matter what protest it is.
Problem is, in a country like France which consider violence a form of Regalia and thus a monopoly of the State, having police officers using abusing their power is way worse than violent protesters. ( a constitution from 1794 even goes as far as basically saying people doing so should be put to death immediately with no form of trial )
I think the majority of the public opinion is at least slightly annoyed about the movement, especially about all the violences about it.
I'm also very active on Yellow Vests facebook pages to try and debate with people, debunk whatever fake news or sophism they could say which basically ends up worsening their popularity, but man, a fair chunk of them are absolute retards spreading fake news through their own ignorance.
