Formula 1 does not have a bright future if it continues as it is now, according to former Renault team boss Flavio Briatore.
The Italian, who left Formula 1 following the 2008 Singapore GP scandal, says the sports needs fixing, especially to offer a better show and reduce costs for the teams.
"F1 is very confused at the moment, there will surely be some changes. There will be a push to change things, because the way it is now, I don't see it having a big future," Briatore was quoted as saying by Autosprint magazine.
"The problem is a bit with everything: the lack of spectacle and unpredictability under normal conditions.
"Also the costs: when we were insisting to have three cars per team, the Federation instead opened the doors to teams who had no budget guarantees whatsoever. I think this was a bad decision.
"There are teams in F1 who are one or two seconds faster compared to a GP2 team, and to be one or two seconds faster, they spend a minimum of 60-70 millions, while GP2 spends three. There's something wrong there."
He added: "You need to do the cars' technology with the spectacle in mind, not the other way around."
Briatore insisted he has no intention to return to Formula 1 in team boss role, claiming he is not missing anything from the sport.
"No. I think that after having won seven titles with two different teams, to add an eighth title wouldn't change anything. I think that winning with Renault in 2005-06 was a miracle, and you can't do miracles all the times.
"Seeing the way it is now, I don't enjoy it anymore, the adrenaline to do it is not there anymore. This is something I don't miss at all."
