It can be done for limited production, but it doesn't fully hide from LIDAR https://www.cnet.com/roadshow/news/bmw-x6-vantablack-paint-c...

From the CNET article:

>> Typically, the lidar unit can spot things from more than 328 feet away.

>> In this case, the company said the darkest of dark BMWs would need to be about 72 feet away before the lasers and ambient light register the moving black hole.

Painting your car in it to avoid lidar

I can't imagine the temperature of that car after sitting in the sun for an hour.

Basically the same as a 99% absorbent black.

In my opinion, if you could afford $35,000 for a Vantablack wrist watch, you can afford another $35,000 for this one too haha. I doubt many of those purchasers were on the bubble.

High end watches aren't priced like regular consumer goods; you can resell them for close to (and sometimes more) than you paid for them, so the "cost" is much much less than the price. What's most interesting about this watch is the steel/vanta combo costs the same as the solid gold version without vanta. Apparently just that small bit of vanta costs more than a large chunk of gold right now.

Not if you pay MSRP; for H. Moser you’ll take a big loss. The material value of the gold is also really small.

It's a bit weird to demonstrate the colour of vantablack by adding a shine to it.

I was thinking the same thing. You can see how they must have felt a black circle on a screen doesn't look too impressive, but this is a rather backwards way of dealing with that. (I would have added shine to the background and watch body but not the face...)

There is a piece of domed sapphire in front of it with an imperfect anti reflective coating.

It can be done and it is legal. In fact, it has been done...

Can someone please explain to me the race to the blackest black?

Painting your car in it to avoid lidar

Because you want to make it easier for people and autonomous vehicles to crash into you?

With all that flashing and shaking I cannot perceive anything with or without VB. Ads guys today lost their roof completely.
