Well it depends on your definition of 'laser headlight'.
First off; I can't imagine a safe way to incorporate laser diodes into headlights without some sort of converter or comparable measure to diffuse the laser light. As you know well, firing a beam directly into someone's eyes is asking for trouble. Moreover, if said person is driving a car, weighing several thousand pounds and travelling at high speed in the opposite direction, well... you have an accident waiting to happen.
That 'marketing ploy' seems fairly straightforward- it clearly states the mechanism being used and why (Very white, white light). Unless you have a simpler and more efficient way (and lasers are more efficient than LED's at higher amperage) to create white light with lasers that DOESN'T blind oncoming drivers, I'd suggest you reconsider your sophistry.
