Currently backing up some of my things, but I may as well upload a few of them into a public spot. They may come in slowly as I find the more interesting things.
First exhibit is my R.C. Pro-Am TAS, which I still insist I have no plans to finish, despite having already done one lap on track 24 by now.
Sure feels like Super Sticky Tires is actually making it harder to deal with sharp turns. Thing is, turning rate is an average of 3 per frame (2-4-2-4 pattern), but the maxed out tires of the third vehicle type shifts momentum by 2 per frame (more precisely, 510/256). When your facing (turning rate) is far from your momentum (tire rate), further turning forces your momentum to shift fast enough to keep up. With a fast tire rate, it takes much longer to get to that exceeding point, to make use of that 3 average to shift momentum, and so it's much harder to properly hug corners.
Alas, my natural max speed gets to 103, just one MPH short of 104. The speed penalty of differing facing-momentum for these sharp turns hardly matters for my natural max speed, as I can easily maintain 96 MPH (game doesn't affect position in finer steps than 8 MPH). Then again, the high tire rate is useful for when I exceed 104 MPH, as it means the speed penalties don't dip my boosted speed back down so quickly. Trade-offs of a good tire, I suppose.
