Why a dash camera?

Early on before noticing dash cams used in Russia we noticed many narrow escapes from reckless drivers in Austin.  So why not set up dash cam of my own?  At first we used smartphone by hand and that was awkward.  Then we purchased a stand that  could support the Sony Camera and that worked fairly well.  The camera has 22 minute limit so we bought a sport Panasonic Action Camera about 3 x 2  Model No GC-XA1BU that when  attached to the stand enables  hours of video on the road.   We started using this action camera in the Fall of 2015 and prepared to add  videos on Austin Traffic as time and preparation permits.
