Yeah, the first movie was kind of a joke in some respects so you had to ignore some things to enjoy it.
"Too Soon" with the Volkswagen (no such thing as too soon with nitrous sprayers! You spray continuously once up to speed; it's not turbo boost from Knight Rider....
)
How the HELL does Vin Diesel know if Paul Walker is double clutching or not? I didn't realize he had Jedi force sense and could tell what his foot is doing in the car behind him while he's racing at high speed.
Besides, if he's planning on doing a lot of racing, he should probably have a dog gear transmission anyway and just jam the thing without a clutch to save time on shifts (hell if it were made today, he should have a double clutch automatic if he actually wants to win the race; personally I don't enjoy them as I like full control of the car at all times, but then I don't race either so....).
They shouldn't be wasting space in the trunk for a stereo if they're racing either....(or at least pull most of it out first).
I'm sure there was more, but I haven't seen it in a few months and I've got to get some sleep.
