Interesting to see a shot capturing the progress of a car which helps determine the rate at which the images were taken.

Wouldn't you have to know its speed?

Of course! I walk past that road everyday so could make an educated guess at 40km/hr. Mind you, my maths skills are poor so I won't be about to start delving any deeper into the calculation!

It was more than one image per second, I can tell you that much. I forgot exactly how quick it was.
