No, it's the hardcore shortcut, where half the lap is skipped. In my humble opinion it's a legal shortcut, but most of all other players think, that it's not ok to use it. If it doesn't get 'repaired' by the devs, then it's obviously ok to use it. I showed all known shortcuts to the devs on day one, their response was, it probably won't get fixed, cause too much effort yada yada. I think everything is ok, as long as no 'respawn' is involved...
