i really like that they turn only at 90 degrees, i suspect that the bikes either consist of
a "burst-teleportation-nano-assembler-disassembler" two would be needed to avoid having to "self-burst-teleportate" (would be too tricky to assemble/disassemble the assembler-disassembler lol), so you'ld basically have a bike consisting of two parts even though it might not show...
or
a "quantum-double-pairing-teleportator* which in effect would mean you're driving two pairs of bikes at once, all existing in the same place, and that the 90-degrees is made by first teleportating the first instance of the bike and then the second. this would be extremely fast, much faster than the solution above
oh shit i just realized i'm a phucking raving loonie
and that this is just a game
. The name, suprisingly enough, is armagetron forums: guru3.sytes.net. Just so you know it is very similar to Armagoshdarn, but there are obvious differences. A) There is a brake. B) You lose 1 point when you die. C) You probably go faster, cycle_speed wise. D) Your walls never end, there is no blast radius, and no wall delay. E) Other little things maybe, like a smaller/bigger grid hard to tell. Hope people enjoy it as a goshdarn alternative, when it's kindof laggy out. (Especially for european goshdarners.) Plus, goshdarn is a good style of play, I jsut made it more like the older versions of Armagetron 
now should that reassure me or should i go and hide? hehe
