I owned one of the fastest production motorcycle a while back. The status symbol often put me into races with high HP cars. Often time, depends what they are, I neglected changing gears. It often made others believe that they were able to keep up with me because they were just couple cars behind me.
That being said, if I saw a bmw 335i pacing me on the freeway while I was riding my Hayabusa, I would've just kept in 6th gear and just rolled it. I did it with an C5Z06 and kept pace with it until 140, and I don't believe a FBO 335i have the same P/W with a Stock Z06 (sub 3200lb car).
Still having doubts? Watch this video. and 335i != Gallardo regardless the mods.
