They are at different spacings. If you follow two rows of dots around, they fall in and out of sync with each other.

Now someone has to go there and drive around it at 33 1/3 rpm at night with a strobe light set to 50 Hz.
Hmm. If the diameter of the circle that the car drives in is 14 meters, that works out as ... 54657 mph. I cannot endorse this from a safety standpoint.
Wait, no, I was working in km instead of m, it's only 54 mph. Should be fine.
It's one revolution every 1.8 seconds. That seems too fast for most roundabouts, but maybe not uncontrollably so.
78 rpm is Formula One territory.
