Tesla Model S Insane Mode P85D - YouTube
it was truly insane!
Damn, those headlights are cool. I wonder if that is an easter egg somehow?
the flashing is because the LEDs are strobing with the camera frame rate, but you are right they seem to be sequenced in a wave.
homage to Knightrider?
Nice! I went to the D event at Hawthorne. It was "insane". Hey I'm San Clemente too. Cheers
Hi Fred, I love San Clemente. I work there but live in hb. How do like your model s textile seats?
Actually, that is how LED lights 'show up' when filmed. They pulse, because of the nature of how LED's are fired.
AFAIK LEDs are not fired but typically supplied with a constant DC voltage. Yes, if that DC voltage is particularly dirty and rippled then you can see some LEDs flicker.
But that car exhibited a particular sequence while it doesn't appear that the other cars had. It also looks like the tail lights were pulsing as well. I suspect this was a deliberate mod. I can't see how rippled DC voltage supplied to LED lamp assemblies would generate such a specific pattern that meets up exactly right in the corner.
LEDs are also frequently driven by PWM for brightness control.
and it is why you get strobing with camera frame rates. Pretty much all LEDs on car exhibit this on camera as they are rarely at full brightness
