Interesting. Curious flickering of the rear lights.

That would be the brake lights coming on as the car brakes going into the corner.

I've noticed this happens for cars with LED rather than incandescent lights.

LEDs on cars are pulsed so they can achieve greater brightness than their dissipation power rating would otherwise allow by overdriving the LEDs but then limiting the pulse duration so the power dissipation over time remains within the limits of the chips, and the magic of persistence of vision makes them appear to be at the greater brightness continuously.  You'll often see they flicker terribly when seen on video because the frequency isn't a multiple of the camera's frame rate.

Oh, I see what you mean now. I hadnít blown it up big enough to see the pulsing. LED lights are always pulsed, so the flickering is the pulsed light in motion. (I shot automotive lighting for OSRAM/SYLVANIA for about 10 years. We learned all sorts of interesting things about auto lighting.)

Subtle playing of light and water and a lone boat that seems to basking in the sun. Just lovely.
