Just to make an example (NASCAR at Indianapolis) - This clip shows how hard it is to pass at Indy with 2 pretty even cars. Slip stream had little to no factor. Starting at 2:30 - Mark Martin was about
2-4 car lengths behind Jimmie Johnson. That went on til' the last lap. Martin never made the pass.
About the speed: IRL, these cars reach Turn 1 in qualifying trim at around 200-205 mph. This would be a tad slower in Race Trim and about the same with the draft.
Now in GT5: I've had my share of racing at Indy online with NASCARS and it is just pure mayhem when it comes to the speed we reach before commencing braking. If you exit off a turn coming into a long
straight at around 160-170, expect to see your speed reach 230+ with a car infront of you towing you along into the next turn. I find this ridiculously absurd (and laughable playing demolition derby online). By the
way, regardless of the tires you use, you will still have the same effect. In regards to the realism of the tires, here's an independent test i made prior to the release of GT5
(click here).
Furthermore, being an online series admin, i personally have a lot of experience pertaining to the draft. It's always been a complaint from all of the participants, especially when we go to draft happy tracks
such as Monza and Le Mans. It affects the dynamics of the race as a whole. If you lose the tow of the draft, then goodbye to you. Likewise, if you are leading and you are alone and turning the fastest and most
consistent laps all day, 2 drivers in tandem from 10 seconds back can tag along and catch you within a few laps.
I really hope that PD is looking at this issue. I personally would like an option to choose between realistic and the way it is now, just so it can cater to both audiences, the casual and the hardcore racers.
