When I ran STK with --track-debug, I saw driveline in this track is too
high above the ground. So, to race here, you must fly in checkline (by
pressing I, come to https://supertuxkart.net/Artist_Debug_Mode to read more), then fall (K), race before checkline. Then, if you'll
fly in checkline again, lap will be counted. This is sole way to
complete all BeBeLiOus' tracks, except Lost Speedway.
