They're supposed o hide in plain sight remember? "Look into the red light people..*flash* right. You did not just see an alien space prank by teleporting water into your helmet. The water came from a faulty fan and pump assembly that extracts moisture. You will report this and find contaminants clogging the holes....."

Most headlight aiming specs are decided based on the height of the headlights from the ground and a certain angle downward from there. The angle is decided based on rated brightness etc. A brighter headlight will be aimed further away from the car whereas a lower powered one will be aimed closer to provide minimum illumination. I'm not completely sure how the minimum distance the driver should be able to see would be deicided. Probably the typical speed that the vehicle is going to be designed for so I guess that would be independant of the model or segment. A fast sedan will have brighter headlamps aimed further down the road from the driver than a slow moving SUV. That's just my guess though.. not too sure... I work in the QC dept so I just get to check the vehicles according to the spec that the design department provides but this is as much as i could gather from my interactions with other departments.

I doubt if any OEM is planning on using lasers directly to illuminate the road. I remember Audi introduced a concept at CES 2014 with laser headlights and a similar debate had ensued then. I work for an auto-OEM and I can tell you that all cars are aimed to avoid the beam going UP i.e into other driver's eyes (unless he's in a go-kart or something.. Ariel atom maybe???). There's not much that can be done when someone gets the headlight reaimed higher which is never recommended by the OEMs

This article http://spectrum.ieee.org/green-tech/advanced-cars/bmw-laser-headlights-slice-through-the-dark(ieee spectrum) shows the actual working using very powerful but very small laser beam which is then diffused into a headlight's non-laser non-coherent beam. The only advantage of this is that a higher power level can be achieved with a very small form factor (smaller reflectors at the back of headlamps means lower costs) which is why OEM's are even trying it out.

"......discovered the oldest known star in the Universe"

Thanks submitter for using a scientifically accurate description rather like in TFA where they say it's the oldest star in the Universe..

The difference is small... Let me clear this for the un-initiated.. if you consider an axis through the center of your head and the centre of your...nether region, and if the head shaking is about this axis, then it means "No" If you consider an axis through the tip of your nose and the back of your head, and if the head shaking is about THIS axis, then it means "Alright" or "affirmative"(especially if the indian you're talking to happens to be a terminator). Not to be confused with "yes". Source: I'm Indian
