This is from my collections of photos titled "DRIVE BY SHOOTINGS", most of the time i have family in the car when we are traveling and they get tired of me always stopping to take photos, so i developed this style of shooting so i wouldn't miss the shot, and keep everybody happy.
It doesn't always work, but I had about an 80% success ratio, Oh, by the way I'm driving as well and 70 years old too.
Have got some unusually shots doing this, the Sony A6000 has made it a lot easier.
