What will they think of next?
How about the opposite? A Model S covered in Vantablack in broad daylight would be a crazy sight.
Ok. Who else really wanna spend more than 10 grands to turn their baby into a glow in the dark zebra?
It's neat for Halloween, but not so much for the other 364 days of the year...
The paint may have some day to day uses. Imagine if the entire (or partial) left or right side of the car could blink on and off to act as a turn signal.
Or if a large number of small blocks of paint could be turned on and off like pixels on your monitor. It could be used to display different messages such as advertisements, logos, or "Stop Tailgating Me!".
If the paint could be made bright enough, emergency vehicles could use it instead of mounting flashing lights on their roof.
The paint could be applied in a more subtle motif. Like using it to create a racing stripe on car when switched to sport mode.
"There's also the question of whether light-up paint steps over the rules for lights on vehicles or could distract other drivers, but those are further down the road."
It already steps over the line. In my state and probably many others, any use of blue lights on vehicles is reserved for law enforcement. If you ask me, people could easily mistake that for a police car.
As for Vantablack, by reflecting no light, you'd likely run down your battery trying to cool the car. Perhaps you need Vantawhite to reflect 9.99999999999% of the light and blind everybody looking at the car. they won't see it that way either, but you'd have a cool car.
Or Vanna White?
