I hope they get everything right this time. From what I've seen of the in-cockpit clips from GT5P, though, they have the cam set too far back for my taste. I want to see from the driver's EYES, not over his shoulder from the back seat. Some of us can't use the chase cams at all, because you tend to overestimate what the steering angle is (and I get distracted by the car itself). This is damn dangerous in a rear driver. I'd rather have the bumper cam stay because then I can concentrate on the road rather than the scenery.
I agree with every single bit you have said so far. I haven't played GT5

yet, and I don't drive in real life, but I have been in the front passenger seat of a car and I know you don't see THAT much of "info" with your eyes.
Chase cam in GT4, for example, actually makes me slower than the "roof cam" I use. Mostly because I don't exactly know how far away from the walls am I, and as you, I get distracted by the car. Funnily enough, changing from chase cam to roof cam is one of the many techniques I used to gold all of the licenses in GT4. 👍
I will never understand how the chase view has a unfair advantage. The only thing it helps with trying to navigate through a bunch of idiots that can't drive and trying to see the best path through and thats about it. I make around the same lap time in every view used so I don't see a difference.
I agree with you too. Unfair advantage? What do people mean with that? It's actually more difficult to drive with it, in my experience, than roof cam or even bumper cam that is also a difficult cam to use for me in GT4, but easier than chase cam.
However, from personal experience, all of the cams get me different lap times. But that is because I'm just used to use roof cam right now.
In all honestly, I was caught between "In Car only", or "A mix of 2 or more, depending on certain situations". I could imagine me switching cameras in risky situations on-line as not to mess up with fellow drivers. Finally choosed "In Car only", because that is as real as it gets.
