Looks good. Definitely try and get some action shots with the camera out the window or something. I made a short video with my sister and I threw in some shots of her stomping on the pedals and moving the shifter and edited those short clips in before she drives into a cardboard target.

Also you can try to have a car drive towards the camera, but swerve at the last minute. You can end the video by taking a turn really fast and dive down an alley while the chaser has to do a handbrake turn to turn around to backtrack. Then from your POV the chaser drives right by you in front and you pull out and take off in the opposite direction.
