I asked about the off-track excursions, speed boosts and car contact issues and was told that they are "watching things" in this non-contest part. I don't know exactly what that means for them, but they were not aware of some issues, so if you have evidence, especially of speed boosts, please post them for me.
I asked if this means we had a free hand to do whatever we want and was told "not really", whatever that means.
I think what it all means is don't get your panties in a bunch, at least until the more serious part, or after they see just how abusive of the demo people can be and what PD needs to do to fix things.
I had to wait for my bandwidth month to end, last night, so that I could download the demo (it should be done soon). Now I should be able to confirm for myself some issues that you find.
