Thanks. It is actually to do with sim racing and the debate over
realism. Many use the TV camera view, i.e. sat on the airbox. And
they get faster times. I say cockpit view should be used, which I do.
But I get a counter that in a real car, one can move around to see
more. Which I reckon is pap. The 15 degrees corresponds to the 15
degrees "look to apex" I use.
Well as someone who has done both sim racing and real racing, you can
tell your competitors that you're right and they're wrong.
You cannot lean your head or somehow crane your neck enough to see even
close to where your tires are in relation to the curbs.
We had this discussion a few years back about how much of their front
wing F1 drivers can see, and I pointed out then that the reason you see
the yellow line painted out beyond the edge of each start location is
that the drivers can't see anything closer to the car:
