There are many advantages to sitting shotgun in the car. Not, I'm not talking about legroom, or being able to play on your phone, I mean the freedom to look at things that aren't directly in front of you.
I often curse my luck when I have to drive around during golden hour. It always feels like some sort of odd torture where great pictures are waved in my face while my camera is out of reach.
Long story short, I was quite happy to experiment with panning and shooting out of the passenger window as the sun set.
