Good, but Too short
Looks great besides the people inside the cars, but it was too short to realy concider it a trailer, much less a teaser.

hmmmm
hmm it looks pretty good =O the graphics n stuff look promising too! =D
Finish it
It's nice, but you should have finished it before submitting it. There is no need for previews in newgrounds. Movies get auto advertising here.
Why bother?
This was way to short and unimpressive to really have a point to submission. I realize that it said "Demo", but maybe a bit more than 3 hours of work should be done before you submit this. When you finish it, you should probably add backgrounds, maybe a story or something. I dunno.
