Laser Lights versus LEDs

BMW recently exhibited their laser light technology at the CES in Las Vegas.

I have 4 questions:

1. Does anyone know if laser lights will be an option for cars in the US?

2. If the delay in having laser lights as an option in the US is regulatory, when will the laws be reviewed?

3. If the laws are revised to allow laser lights, how long will it take for BMW to bring the lights to the US?

4. What are the benefits of laser lights over LED's?

Thanks.
