However, as the show climbed up the ratings and became more popular, “the guys who raced on the tracks decided they would challenge the TV guys, since there wasn’t danger of being arrested and losing their licenses.” Now, with sponsors and appearance deals given their rise to fame, “it was a natural transition for these guys to upgrade to track type race cars themselves.”
Another fan chimed in to say that the show is “99% real.” “The 1% is the fact that the road is rented out by Discovery/Pilgrim Studios and blocked off by the cops,” they add.
So Street Outlaws is not exactly fake by any means, it’s just produced and regulated so that filming can remain legit while still trying to keep the illusions up for audiences.
