I agree, world scaling is a good thing. Just installed Automobilista 2 and the first thing i noticed was that the car seemed awfully small. In PCars2 and ACC2 I would look at my elbow and my shoulders while wearing the headset and make my scale adjustments from there. You could sense when the scale was right, hand and elbows appear where the should in respect to reality. I feel as though I could reach out toward the other side of the car. I would fine tune to my liking, minor tweaks and all, but usually ended up with a much larger car than in Automobilista 2. I find it much easier to place a car, it just feels a bit more real. And yes, I do find myself looking at my watch, only to realize my in game hand doesn't have one.
