They need to apply as they do with everything in GT, a "homogenizing" effect to all cars. If they do TCS, they want to do it the same for everything . Same with ASM (most cars don't have it), and ABS (cars before a certain year shouldn't have it, and some after).
To me, it is completely obvious that the way they apply homogenization to other aspects of GT is also being done here with the TCS on/off.
You are also obfiscating by moving us to takling about a different topic. We're not discussing whether the inclusion of TCS to all cars in a uniform manner is accurate for all vehicles based on whether they have TCS in the first place. We're discussing whether the On/Off value is unique to each car, and after finding out that it is, talking about why it is. The pattern is very conclusive, to the point that it's not just "guessing".
Here's the logic:
Because we know that ABS, TCS, and ASM are not on all vehicles but PD has included them on all of them anyway, thereby homogenizing the experience across all cars, it stands to sound reason that when they give all of them a 10 level adjustment for the feature, that it is also because of their desire to homogenize the experience. Then, when you look at the fact that the TCS setting for each car is remembered for the car itself and not a global setting, that fits with the real-life effect that you do not have a "global" setting in your person, that somehow communicates with every car you touch that (if it has TCS) it should turn off when it senses your presence.
So, it's two-fold. 1, PD wants to include a setting that is applied to all cars the same way, for ease of programming, and so the users across all skill levels start out easy (with TCS ON) and have a homogenized experience when they touch the game. 2, it is so that PD can make sure that a user who thinks he doesn't need TCS for a lower powered car wouldn't be thrown into a situation where he jumps into a high powered car and has difficulty. PD likes to hold the user's hand and help the newer drivers progress. Making you deliberately turn off TCS accomplishes that. It's not guessing. IT's a theory supported by ALL of the evidence.
On the 10-level incremental adjustment for TCS on cars that may not have 10, I think you may be forgetting something that I assume you hold dear, and is in your PSN and Tuna name -- that having something on "10" or heck, even "11" means nothing. The level of TCS has nothing to do with the arbitrary number chosen to represent it. If one car has only an on/off setting for TCS, and PD gives it 10, it doesn't mean it would be 10 times greater than real life, just that they split it into 10 increments so that the user again, has a homogenized experience across all cars. The authenticity of the incremental choice vs only an on/off choice is again, apparently homogenized for us intentionally.
But but... this one goes to eleven!
Honestly Doc, the fact that I need to explain, re-explain, and then defend my positions so much with you leads me to believe that you, at least a little bit, enjoy being intellectually combative with me. As far as being "careful" about assumptions goes... I'd hope that you are careful enough not to assume anything about someone based on the fact they don't have any letters after their name, which I don't.
With respect, and yes, a little frustration,
