Both of you are missing something very simple. The new (it's actually been used for a few years now) GPS system is a tool to help the judges. It doesn't take place of them. You still need live judges to look over the data, as the data itself could never choose the winner.
The speed, angle, and proximity would be analyzed and graded during this time.
For tandems,
Points deducted for straightening out......
or
chase car comming in too fast and causing a crash.
or
lead car obviously slows down the pace too much and instigates a crash.
I think a gt5 computer programmer could set something up as easy as this????
You're oversimplifying...
There is a lot more to it than that, and a lot more possible scenarios, than what you have listed.
Look at all the games that have tried to do a drift scoring system. GT5
(hugely inaccurate), Forza 3 (even worse), and the aforementioned D1GP (the worst of the bunch). All they have served to do is create bad drifting habits (check F3 online to see examples of this), as the systems are too rigid (CPU Data Acquisition) to be able to differentiate between all the different criteria necessary to determine a "good" drift (Angle/Style/Smoke/Speed only being the main judging points).
Furthermore, for those of you who think D1/Formula D is going to be a part of GT5 like WRC/NASCAR, you might want to consider something. WRC and NASCAR have been touted as the new big series in the game. If this (D1) isn't some big surprise at E3, I would let some of that enthusiasm die down. D1 is a huge series in Japan. It's inclusion would be big news, and likely would have been mentioned by now, along side WRC/NASCAR.
It's much more likely that PD will include more D1GP/Formula D vehicles, and scrap any plans for a true D1 style scoring system as Kaz is more than likely very much aware of the inherent problems with automating a subjective scoring system. The "Drift Trial" mode (from GT5
) will most likely be what is in the full game, with challenges based around that system.
