One bit of advice: you don't necessarily have to drive fast to test airflow. The air behaves pretty much the same at 30 mph as it does at 70 mph. That may make it easier to find a suitable road to do this.

Have fun! Sounds like you're going beyond a simple examination of the rear glass (which you could have done on your own using just the Prius with the camera inside).
