If you notice... I believe that Civic (yellow is it?) has drag slicks in the street racing video I could be wrong been a while since i've seen it... the guy in the Viper wasn't toooo far behind but he still lost... Had the race been just a bit longer the Viper would of pulled ahead cause of its greater top end.
Remember also, even though the Viper is fast in the quarter, its not built for it. They are beatable... they're more tuned for road racing. But yeah, he lost to a well tuned Civic... big deal. Its not like every Civic is like that so i'm not worrying. haha
