Live For Speed team have recently released an update (0.6B), that makes it possible to setup an open track. So you can choose which route to take yourself. This also made some previously inaccessible parts of track accessible. One of the parts is this small oval part of the track, with an uphill/downhill turn. Great for practicing mid-speed drifts.
To set up an Open Track, you must hold CTRL while in the track browser. Then choose X or Y configuration depending on the direction you want to drive. Also note the X or Y tag in the server browsers.
