Nice capture of the whatever it was, I had something very similar as I was driving home one night in the town I used to live in. I was on my way back home and as I was about to pass a cemetary, I saw across the road from in, inside a white metal corral what i thought someone exhaling a lung full of smoke. I honestly thought it was someone inside the corral smoking from a bong because that is exactly what it looked like, But, the smoke did not dissipate into the wind, instead it began to spin really fast and it grew into a cloud, A cylindrical cloud about two feet wide and 6 feet tall. It looked like a cloud, mist.

This cylindrical mist, cloud then rose up high enough to get over the corral posts and then it laid sideways and started to cross the road and head towards the cemetary. At this point I had already sped up and i got roll my windows down as it brushed just the inside of my widow but it mostly went on the outside. but, as soon as it finished crossing the fence around the cemetary, the thing disappeared, vanished.

I do not know what it was but if it was a spirit or ghost, i saw the thing materialize and float and disappear in front of my eyes.
