Daniel Ricciardo says Formula 1 drivers are "pretty frustrated" at being left in the dark over major developments such as the proposal to introduce a revised weekend format in 2020.
F1 is understood to be keen on trialling a revised weekend format at select grands prix in 2020 that would include qualifying races with grids set in reverse championship order.
But the proposal has been met with strong opposition from drivers, with Ricciardo the latest to speak out.
Ricciardo stressed that the widespread opposition was not part of any coordinated push agreed among members of the Grand Prix Drivers' Association, but that drivers were unhappy not to have been consulted on the prospect of such major changes.
"That's something which us as drivers are sometimes pretty frustrated about," Ricciardo said.
"Things will get put in front of us [by the media] - 'they [the rulemakers] are talking about this, they're actually fairly deep into this discussion' - and we're like, well, why haven't we been told about this?
"That's why we've been trying to put in more of a team effort, the last few years, to make sure we are involved a lot more.
"Because over the years some things have been decided without addressing us drivers - and, you know, whether we're paying the bills or not, we are the core of the whole show.
"Especially if it's something that we feel strongly on, then I think our opinion is more valuable than really anyone else's. I think we're making progress, but they don't always like to involve us - in the past they haven't."
Championship leader Lewis Hamilton said that F1 entertaining such experiments at this time was not compatible with its impending 2021 rules overhaul.
When asked by Autosport whether he shared Hamilton's disapproval over the timing of the proposal, Ricciardo said: "I don't think it's the right time.
"I think if 2021 [delivers] what it should, then there's no reason to change anything of the format.
"And I think as well it would then dilute a lot of the weekend. It's like some other sports I follow, the product becomes diluted if you then have reverse-grid races, this and that.
"2021, I think that's enough changing. I think that [suggestion] is a bit desperate, and I don't think we're in a desperate time at all.
"As I said, there's some [sports] - like, I love the UFC [Ultimate Fighting Championship], the mixed martial arts and all that, and it got to a point where they were having fights on every weekend, and it's great for fans, you get to see a fight all the time, but you become less excited, less interested, because it's always in front of you.
"So I think like that with the races, if there's always a race on, and if they're reversed-grid and then kind of manipulating the result a little bit, I think it loses some of its value and some of its core.
"I'd prefer to keep that part for tradition."
