FIA President Jean Todt believes some of the drivers have "short memories" over comments made regarding the introduction of the halo device.
After a signed letter from the directors of the Grand Prix drivers association (GPDA) in 2015 regarding head protection, Todt believes he heeded their request and put it straight into action.
Ever since the halo was chosen by the FIA as the primary choice for protecting the drivers' heads, the device has been regularly criticised as a poor choice and Todt is unimpressed by some of the comments that have been made.
Speaking at a media briefing in London, Todt said: "It is simply a childish game. I think it’s very inappropriate whoever you are to publicly deny something which is introduced."
"It is short memories and it was a request from the drivers. On December 16, 2015, I got a letter that was signed by [GPDA directors] Jenson Button, Sebastian Vettel and Alex Wurz, urging us to decide for head protection for the drivers, and I said, 'We are there. We will listen.'
"Immediately we asked the technical people as a priority to see what could come out, and on July 27, 2016 [the drivers] knew a meeting was going to happen – and they said: 'Don't be weak. Please respect what we have asked you on safety'. So we committed to taking that into consideration.
"I must say I am so surprised. I love F1 but I hate this part of F1. You have people who don't [keep] their word. For me we are talking about the biggest asset in life: it is loyalty and [keeping] a word and having the respect of what you have been undertaking. We have respected that and some have forgotten that, but that is where we are."
Similar comments have also been made with regards to the change in power unit regulations for the 2021 season and beyond, the FIA recently made public a series of basic proposals, however, this has still not pleased some of the teams as they believe radical changes will need to be made, causing more money to be spent in designing a new power unit.
The former Ferrari boss is keen to ensure the teams do respect what was agreed and is also optimistic the new regulations will potentially attract new manufacturers into Formula 1 and stay for the long-term while ensuring the current teams remain happy.
"Unfortunately there is a very selective memory,” he added. "A few months ago we all sat together and we all agreed unanimously on certain adaptations of the engine for the future. So I’m intending that they will respect what they agreed.”
"I’ve been talking with some potential new entrants, they are interested to come in but they want to know what the rules of the game are. I think it’s a fair request and we need to give that as soon as possible. I am optimistic that we will be able to find a solution.
"While wanting to entice new entrants, it was important to be “fair” to the existing manufacturers given their loyalty, clearly we don’t want to lose anybody."
