This is not available yet on Infiniti models but has been on the BM-7 and now the BM-3. I'm posting just to show the direction headlamp technology is going. US car makers are often dissed for being sooooo far behind the other car makers with headlamp improvement but it's not about cost or intelligence. US laws are very slow to keep change with the technology it is difficult to get any productive effort from law makers.

I think this is an excellent example of intuitive design and technology that makes driving safer for everyone.
