Live commentary

I should suggest live commentary, where the commentator talks or not (depending on the voting choices), and shouts out these things that I suggest:
"He's locked up!"
"[Driver name] has overtaken [Driver name] for [position number]!"
"[Driver name] wins the [race name] for [team name]!"
"[Driver name] goes into the pits!"
"[Team name] wins the Constructors Championship!"
"He's retiring from the race!"
"[Driver name] retires from the race!"
"It's lights out and it's go, go, go!"
"Will he be able to make it?"
"[Driver name] ran out of fuel!"
"Let's take a look at the starting grid for today's race!"
"Glorious move by [driver name]!!!"
"[Driver name] wins the World Championship of Season [number]!"
"He's losing pace and is slowing down!"
"All five lights are on!"
"They go wheel to wheel!"
"He's extending the gap!"
"He's gaining on [driver name]!"
"Oh no!"
"[Driver name] finishes second!"
"[Driver name] rounds out the podium!"
"[Driver name] gets the fastest lap!"
If you have more for the commentator to say, type it down below.

"[Driver name] with DRS goes round the [inside or outside]!"

In many leagues the race speed is set to 2x.  The commentator's tongue will fall off.  RAM is already overloaded.

(Driver name)'s lost it! (name) flies into the barriers!
(Driver name)'s had a moment but is back at racing pace.

For the app it would not be workable IMO. First off, because of audio, the app size would have to increase by a serious amount. Secondly, it would add to the amount of data to go into the app during race, slowing down the simulator data coming in.  And I would turn it off as i don’t use sound in the game anyway.
So for me is a no go

We had it before for a while but it couldn't read out custom names. Car number calling out might be an option though 1-32

Far more important things to work on instead of this...

Yeah 4D....

I think a box at the top of the screen with commentary would be nice, but actual voice would be too buggy. And having driver communication like on Motorsport Manager, when he/she tells you the tires are going or similar

Also some managers rename their drivers

Therefore Text is the obvious solution
