Add formation lap

Adding a formation lap would be very cool as when you join a race you get a 1/2 minute wait so maybe a formation lap in between the timer would be very cool.

This does not change anything in the game, so the developers will not do this. And there's no need...

It’s better than just waiting for 2 minutes and nothing is going on. Also small additions like this is what makes a good game to a great game

There are a lot of very serious problems in this game, such as the currently existing league system with inactive rookies and professionals, a bunch of abandoned leagues that attract promising rookies and aggravate the problem of their shortage, and in comparison with this, minor fixes that do not affect anything simply fade. 
For reference: while the timer is running, elite players usually discuss the upcoming race among themselves in a chat, and therefore they do not care at all whether the cars are standing or driving. You, too, will soon get into the elite and will participate in it. As far as I remember, no one has put forward your proposal yet, and no one will do anything for the sake of one person, mass support is needed here :)

As you said no one has put my proposal cause it’s a new idea. Inactive players are always an issue in every game. The only way to get rid of inactive players and dead leagues are the Hosts and idk if there are co-hosts to help the host. Plus I doubt a formation lap can hurt anyone. 

I'm not arguing that formation lap won't hurt, but it takes a lot of lines of code to create it, and the question arises, is it necessary at the moment if there are more serious problems?

New updates usually bring new bugs, and this game has slow developers who will fix these bugs for a couple of months (and they will also write a code for a month) :)

If this game had more developers who would have time to work on important problems at the same time, come up with innovations in the game process and at the same time make small visual suggestions that do not change the gameplay, then I would only be for your suggestion :)

You're probably new to this game, and therefore you don't understand that the problem of inactive leagues is not what you're talking about. Even an experienced player in this game without having several friends who will race in this league cannot create an active league. And people, especially beginners, create these leagues, and these leagues of 1-2 players are superfluous, but they pull on active newcomers who, entering such a league, think that the game is abandoned. The solution to this problem lies in reducing the number of leagues. The fewer of them, the greater the asset in each. Okay, we went into what you can read in other topics on the forum, so I won't write anything else about leagues...

I agree with your concerns with inactive players. But it’s a very hard fix at the moment. If this game builds a community more devs and people can help at building the game.

 Currently this game is missing a proper community for example in YT there’s only one good video about this game. There is no official discord or anything besides these forums that the majority of people don’t use. I think this game mostly suffers from a proper community as it’s a big part as this is the best F1/open wheel racing mobile game in my opinion and has a small support behind it.

The reason I’m giving small “useless” ideas is because I know this game is small in a way. So I don’t wanna bring something like a “solo career mode” because it’s very difficult and complex.

You can join the race any time between after the qualifying ends from your league page. The option to join race becomes active on the home screen 3 minutes before start.

So it can be anywhere upto 7-8 minutes wait if you join from the league page. So what do we do next for those people? Play national anthems? The simplest workaround is if someone doesn’t like waiting, just join when there is very less time left to the start.
Stuff like formation laps don’t add anything of value to the game, and it would be worthwhile if the developers’ energy and focus continues to be directed towards other things that need to be fixed in the game.

This has been proposed before and rejected as it is just a cosmetic change.

Idiosyncrasy of the race setup...

If you look at the live compounds screen in race, you will always see that the first stint shows 1 lap less than your actual stint length.  That must mean something.

IMHO, that means that we do one full tilt racing start parade lap, followed by a rolling start, followed by the ability to use boost and DRS.

Fair enough Kevin
