Haha would this even be legal?

Nevermind - it’s not even feasible

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

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

It can be done for limited production, but it doesn't fully hide from LIDAR

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.

LIDAR is most effective at a distance from the license plate, headlight, and chrome reflective parts of a car. There is a laser absorbing product called VEIL made specifically for reducing these reflections.
