light streak photography of vehicle in the middle of the street near rocky mountain

My friend and I were heading back home to San Francisco from Yosemite National Park late one night when we noticed that there was a very bright full moon out. As we drove we suddenly came across this view of El Capitan illuminated by the moonlight, with the pinpoints of climbers’ headlamps dotted around the famous wall. We pulled off and I took this long exposure that also captures some of the stars, and the tail lights of a car driving past.
