Well i brought the advantages into the discussion, but there are really some certain disadvantages with that view.
Well you have a better suround view, thats true.
But you only can guess whats going on behind you and only guess whether the car behind you will start an attack or not, i am often left in the situation where i prefer to open the door instead of closing it and might causing a crash, because i am not 100% sure whats going on behind me. Mirrors are definately a big advantage there.
The second disadvantage i can think of is, that you are not actually on the height of the car, thats obvious since you are flying behind the car. I actually always struggle on courses like South City because of the fact that i need to turn earlier then my actual position is and cant see round corners
.
The third disadvantage which comes to my mind is a but hard to explain for me in english. But if you have driven this dynamic chase view you will know what i mean. When you are turning hard the direction of the camera is not the direction your car is actually heading to. Which combined with my second point makes it harder then in cockpit view to estimate how much you should steer and how much to use the throttle since you dont really have the actual position.
These points combined might also explain for me, why i alway have been good at Westhill and Kyoto National and always struggled to come up to pace on circuits like SO, BL and As Cadet, naming especially hairpins on other circuits where i seem to lose time...
This is no whining, just explaining that now people picking on the "huuuuuge" advantages but telling there are also these and maybe other disadvantages.
