the changes you've made to redzone (adding +10 with every new developed part) is a good idea but the problem is it will never go down as the season progresses, and it should go down, the better your team (HQ) is the quicker you should improve reliability of your cars. this also happens in real formula 1. i dont know if it's possible to implement this element to the asset.file.
im just 3 races into the season so i dont know how this redzone-punishment will work out... we'll see.
yes, it is a challenge but too static, it should be dynamic...
As a concept it works fine, the AI don't mind it too much. It does go down as the season progresses, but it will return to normal the next season. It offers the player a dilemma, reliability vs performance. In the Vanilla game, it was easy to get things to 70 reliability, and then reliability means nothing. With this, the more you push the bounds of performance, the more you have to contend with the increased red zone problems. It also promotes using the -X red zones aspects. And it makes the mechanics who can do that as a skill kings!
As red zone is reset to 20% next season, there is no long term effects. Red zones USED to carry over in the first version of the game, but that was a bug. The game was using taking the '+/- X% red zone' and used that in next years part, instead of the Final Performance Value.
You can easily race in the red zone. It really doesn't slow the car at all. It's only an issue if it gets to 0, where you retire or snail around the racetrack. So it can easily be handled, but still will make you look after your parts, or pit to repair them, or hope they don't break. It's a feature I think works well from testing, but things like this is always going to boil down to personal taste. I have my vision, lots of others will have different visions.
I'd love to implement randomness into it, dynamic and not a static +10% but alas that wasn't possible. Yet.
I haven't tried adding lots of new components. I could easily make loads, different values, different red zones. Etc. It's on my to do list to test to see if it's possible. I've not done it yet because (1) I don't know if the game will use my newly created car components, it maybe pre programmed to only use the ones already created and (2) each component has an 'image' which states what the component does - and I am no artist so I don't edit them, or create new ones. Which is why I didn't add the +10% red zone to the on screen display.
It's something to try one day.
