How about ''Car topped out at whatever'' ''Ineed NOS!''
Ok. speed at max rpm in top gear will not be changed by nitrous :[

And... the reverse lights on the green eclipse during the unexplained spinout in the beginning?

The fact that sometimes only the fronts spin, then only the rears, then all 4?
Lol.
And... apparently NOS makes your floor fall out.
Then come back.
...And apparently under a large shot of NOS the only danger is the intake manifold being damaged.

I could go on all day.
I hate F&F :-p
