Video of cars driving under a bridge - where to find ??

edit

Does anybody know of a publically available download of a video format that OpenCV can open (ex. avi, mp4, wmv, etc.) that shows cars driving under a bridge? I'm planning on making a car counting tutorial and need a good video to work with for this.

The video does not have to be especially long or high resolution. I'm looking for something similar to the following:

https://www.youtube.com/watch?v=z1Cvn... https://www.youtube.com/watch?v=w6gs1... https://www.youtube.com/watch?v=1Hplj...

But before the video has been modified and available for download.

Before somebody responds "get off your lazy duff and go record cars at any nearby highway for 5 minutes", I live in Detroit and it's currently 20 deg. F outside and the road is snow covered and it's still snowing heavily, and the weather forecast calls for the temperature to not get above freezing for the next week at least, and I'm looking for footage where the cars and/or road are not covered in snow, so recording video in person is not an option for me in the immediate future.

Any suggestions would be greatly appreciated.
