Damage settings: old discussion revived, I see only nonsense

There are some relevant posts about Damage Settings, also in the FAQs. My tests have resulted only in nonsense however and I'd like to see more clearly.
There are 3 basic settings you can set to control the damage:

GP4Tweaker > Damage Coefficient > makes all cars more or less resistant, but has NO impact on influencing retirement / non-retirement. A non-retirement means the car's motor is still ON and the car has enough parts remaining to return to the pits to repair.
CSM.ini > [MISC] > damage=xxxx > any value set here (it doesn't matter which value) will make AI cars indestructible, but again will NOT influence the motor state, a hard hit will shut down the motor and make the car retire although the car has no damage.
Settings\Damage.ini > Here a lot of settings are possible, but only the less interesting ones, the entries 1 and 4, will work and give results turning GP4 into an arcade game. The default values are:

[Damage]
;the comment is the game default value.
;it's not necessary to have it, but it might be good for reference
DamageCarsBounce =32 ;32
DamageWalls =7424 ;7424
DamageCars =8192 ;8192
DamageWallsBounce =16 ;16
NoseCone =2 ;2
RightWing =130 ;130
LeftWing =130 ;130
RightWingFence =66 ;66
LeftWingFence =66 ;66
RightFrontSuspension =136 ;136
RightFrontWheel =136 ;136
LeftFrontSuspension =68 ;68
LeftFrontWheel =68 ;68
RightSidePod =8 ;8
LeftSidepod =4 ;4
CarRear =12 ;12
RightRearSuspension =34 ;34
RightRearWheel =34 ;34
LeftRearSuspension =17 ;17
LeftRearWheel =17 ;17
EntireRearWing =256 ;256
RightRearWing =256 ;256
LeftRearWing =256 ;256
TopRearWing =256 ;256
LeftBargeBoard =8 ;8
RightBargeBoard =4 ;4

All values except 1 and 4 have no logical consequence, no visible impact that makes them different from the default values.

Here my precise question: How to make AI cars always keep their motor ON whatever crash they sustain ? If the settings allow that, then maybe I can test the values further. And no, the entries 2 and 3 do nothing.
Even if I am wrong and some values make sense, GP4 would need a tweaker for the motor state (ON or OFF at specific values) to turn the game in a realistic simulation IMO.

Thanks,
