From the developers of PURE, Split Second lets players “trigger destructive events on the track in order to impede their opponents (or themselves, if they’re not on top of their respective games).” Video after the break.
However, rather than participating in high-speed (probably illegal) street racing for your own amusement, it looks like Split/Second will be placing your automotive exploits in front of an enraptured televised audience.
