Hi KO, Not entirely but a similar effect. Often tail lights will blink faster than 60 Hz, you can estimate how much by sweeping your eyes across the lights at night and comparing the number of flashes that you see to the number that you get from a 60 Hz indicator light such as a LED or neon bulb.

He should have rotated it 90 degrees before posting, though, since most of the clip was shot in landscape mode. I think Cor probably nailed it on the taillights. Interesting if Tesla's are indeed full on when braking. Most factory LED taillights are never full on, but are pulsed even when at full brightness. This lets the drivers overdrive the LEDs for more apparent brightness, without overheating them. The eye's persistence of vision fills in the off-time unless you or the lights move. (Interesting that a circuit to do this is presumably cheaper than higher-native-brightness LEDs.)
