Gorgeous animation, but thematics fall short.
Setting aside the current level of skill and vision among the average Newgrounds artist, this is definitely a cut above in terms of visual development and animation. Wonderfully done through and through, this is definitely quite the eye candy. Perhaps the best I've seen with Flash ever.
With that said, it should be noted that despite such great leaps in animation (and arguably sound, though it needs an original score), there isn't much else. For a trailer, understandable, but what truly nags at the mind would be the fact that every American action flick cliche is more or less brought out in this (as was noted by Arandomerican).
Even so, what got to me the most, was little bits of unrealism that worked it's way into the feature. Rather than go over the many, just the one that really got to me... I take it the artist has never visited the L.A. area... where is this magic road you feature in the beginning of this? The City of Los Angeles is surrounded by other cities and freeways. Also, I have yet to see a sign with "Los Angeles, The City of Angels" anywhere while driving, though perhaps I missed it on my X thousand times going about there...
I think it would be really awesome if the film was geographically correct, but I suppose that might be a little much to ask for...
Still, this teaser is not without merit, but if it truly wishes to be the "greatest animation on Newgrounds" it needs substance, which is hopefully what the finished product will bring. I eagerly await to see whether this becomes something of dreams, or something of nightmares... just don't go too Hollywood ;)
