I can confirm there seems to be something up with their chassis choices. Every team had severely bad tyre wear. Inters on my car were lasting 21-23 laps, they were lucky to get 13.
Oddly, this is my second season with the updated mod, and I never saw any of this in the previous season. Maybe they are wasting all their cash on parts in the prior year, and have nothing to spend on the car? Might explain how ZRT went from 10th best to 1st in 2 seasons. [EDIT] - I did note poor furl economy of some cars, come to think of it.
Just checked Lucatelli, at the end of their second ERS season, and their chassis is all under 1 star.
Odd, I've never seen them radically change their chassis decisions. I've only added a couple of 'price reductions' of the chassis parts, in creased the max stat for engines a little. I've not touched how the AI select their chassis - so I am reluctant to see if this is actually my mod.
So questions for you both:
What where their finances like before you joined them?
Do you get the same thing in the unmodded game (using the new 1.2 version)?
What was their final position in the previous year? - and what was their Merit Payment rules?
The latter is a potential for why they can't build a decent car, but that should only worry the worst teams, the better teams should end up with far more then before. It's really the only idea I have. Why they would struggle with that.
Otherwise I am not too worried - the AI have a tendency to naturally make poor decisions. I have seen many low star chassis in Tier 2/3 during Vanilla. Even in WMC it was common to see many teams simple have a weak 2* average chassis. But do another season, let me know if the trend continues - if it's consistently bad, then I'll push further. Espionage as many teams as you can, and let me know.
Meanwhile, I'll look at the Chassis Weightings each team has, to if you're just picking teams which priorities other things. I assume your player stats are quite low still? Which means you're applications are being rejected from bigger teams who perhaps are developing thier chassis. I have a feeling this may be the reason.
As for tyre wear, chassis choices are making a much larger difference, as does driver smoothness, their heat and how the AI is using them. However. that level of difference is extreme. Interns specifically have far less change (2 laps) between the best chassis and worst chassis. Do you have much better drivers who are not locking up, while the AI have drivers that do?
