Ups, I've totally forgot it: Congratulatios BJ!!!
Well, replays are uploaded, so I proceed to answer this question
IRC rule interpretation question for the new track: are spiraling jumps off ramps allowed? By spiraling jumps, I refer to the classic trick where one enters the ramp coasting it along its edge so that the car rolls outward along the ramp guardrail and then takes off rotated sideways:

As you can see in this screenshot, which corresponds to the furthest outward position during the trick, the right side wheels are just above the guardrail, thus the car seems to be OWOOT. The polemic point that concerns me is whether grinding the walls as one could do with a skateboard should be counted as illegal exploitation of a collision bug (even though this situation is not completely distinct from the boulevard bump bug...)
Well, I don't like this bug, it think (as you mentioned) it goes against one of the rules, but since I'm allowing it since long ago, I'm not considering it a penalization. Perhaps in the future I will, but not for now (I have others things in mind to do before that). When you check the replays, you'll see that Mark and Ayrton already used this bug on TATETI, and (in my opinion) they are on the very edge of the penalization.
BTW, in my opinion this bug is quite distinct from the boulebard bump jump (you aren't going through the element), but it isn't that different from the... mmmmmmh (damn it, I forgot the name of the element and I don't have Stunts on this computer to check)... let's say: "round tunnel" bug, which I also consider it goes against the same rule, but I'm also allowing it since long ago and I won't change that in the short-term.
