nah, watching the video over and over, i gotta agree with scotty. the viper didnt floor it off the line. caught up to the gsr within a fraction of a second, and thought ah f**k it and stopped riding the gas. if you watcch it, the viper catches up and couldve taken the gsr when you hear the guy go, "oh s**t", but the viper let the gsr have it.
