Seperate Jet walls created by two different Lightcycles
Jetwalls in Tron Legacy.
The Jetwall is unbreakable barricade created by a Lightcycle when racing in a lightcycle game on a Game Grid. The lightcycle drivers are in constant motion on the Game Grid, creating a jetwall behind them as they move. Each jetwall matches the same color of their lightcycle. If a driver hits a wall either by accident or by having no more room to move, he is derezzed and the last driver standing wins.
In the TR2N Proof-of-Concept trailer shown at Comic-Con '08, the lightcycles still leave a jetwall behind them. However, since the lightcycles turn more smoothly now, the walls also curve and can be sustained in midair. Also, another cyclist does not immediately die if they hit a wall. Instead, their cycle will bounce off of it as if it were a real wall. However, a head-on collision will destroy the cycle.
