Really important question, but unfortunately the article doesn't mentions it. What do mention is that for a successful identification only the three-quarter of the face is needed.
The article doesn't mention it directly, but it seems it will scan actively.
Thanks for the info, the article says that the creating of a similar system is also in progress in the United Arab Emirates.
Seems like it, the captured photos (in 360 degrees) will be compared within milliseconds with the list of the wanted criminals in the central database. Even when the car is moving with 120 kmph.
