I can definitely see you're improving. Couple of improvements to make:
Intro was too long for a movie of that length. And when we got into the main part of the video, nothing much happened. Just two cars driving along...
When you did the nice zooming in and out fading thingy, you should always fade in while the camera is zooming in/out, not before it starts. The same applies to the end of each clip: fade out before the camera stops zooming.
There was one moment when the camera went crazy; when that happens, you have to re-film it because it doesn't look very good and looks a little lazy.
But, you definitely are imporiving; keep going!
