That's my opinion. Cockpit is my favourite view, a bad cockpit view such as the Murciélago's can ruin the entire car for me. All the wrong sounds make lots of cars less enjoyable to drive than they should be too.
Edit: Just realised I said the fact that most players don't notice or care is sad. Well, it is for the same reasons, there's no pressure from players nor brands to put in more effort.
If it's too small for most people to notice perhaps it's not a very big deal. I haven't tried the Murcielago since GT5 though, so I can't remember what it's like. I usually stick to the classic cars
What math? We know the number of cars in the game which is heavily bloated (even Premiums) and we know neither how big their car modelling team really is, nor if they worked on cars the entire time. So many unknown variables you can bend it all you want until it fits.
A single person at their studios may work that long on an individual model, but what's with the Huayras, Mustangs, Veyrons, the dozens of related cars that were there before GT6 where one is based on another. Six months spent on every single car is not true.
We can count just the unique models (from a 3D modeling point of view), of which there were 83 by the time the game launched:
If there are 83 cars to be made and each car takes 6 months, it would take 83*6 = 498 months to complete them all.
If they had 30 months between GT5 and GT6 to complete that work it would require 498 / 30 = 16.6 modelers.
Add to that the new models which are modifications of already existing models, such as the Abarth 500, the street version of the KTM crossbow etc. There were 10 such cars in GT6 at launch. If we're being generous and say that each one of those cars requires 2 months of work we need to add another 20 months worth of work.
So in total we have 518 months worth of work. Divided by 30 months that is 17.7 modelers.
In the ending credits of GT6 there are 18 car modelers, plus 19 car modeling assistants, plus 12 car modeling chiefs, plus seven car modeling directors. Even if only the car modelers are doing actual work on the cars the 6 months per car makes perfect sense.
Also, the position of the driver's eye view has very little to do with actual modeling time. You're comparing a task that can probably be done in less than an hour to a whole project that takes six months. As if a substantial amount of those six months would be used to place the camera views.
