Someone crossed the slightly bowed wooden footbridge during my exposure ... :roll: ... it was too long for the lights coming off the petrol/gas station, anyway ...

Sorry.
True blooper.

if you now knew the frequency of that person walking, you could determine the speed of that car!

Actually, I had the same problem with that bridge i took the images in London from, I always had to make sure no bus or larger vehicle was crossing

Well, you might want to do the calculations for me? But then ... ah well, you don't know the frequency of their steps, either... Hmph :scratch:
