drone use in racing

Has any one had experience with using new gen video drones in filming racing?
Typhoon g500 4k, Phantoom e ETC.
Youtube has some good videos from Europe rally and tin cup dirt races.

It would be great hoovering outside track and best corners for great racing footage.

Any info appreciated.
