Really nice so far, I'm impressed!

Something you could do that I really like in chases is to mount the camera on the front bumper of the car facing backwards filming your front tire as you turns and also get a glimps of the pursuer.

You can mount it with some papertubes and tape without damaging the cars or camera I think.

Another good view is to mount the camera on the rear side window facing forward.

I think you get more action with such views.

And btw I have thought of doing the same some time I have one running and one crashed Volvo PV after all
