There are, broadly speaking, two types of drone.
One is a terrifying automated death machine that Western governments (mainly the USA) use to conduct anti-terrorism strikes in nations they haven't technically declared war on. The other is about the size of a pizza box, sports four to eight propellers and can fly to heights that can become bothersome to curtain-twitching neighbours.
The following video concerns the latter - and you're about to wish you owned one.
FPV (first person view) racing is the next generation of RC car racing: in order to maintain control of the dizzying speeds reached by their drones, the racers are fed a live video feed of what their drone is "seeing" via a video goggle headset.
This footage shows 30 FPV racers negotiating a tight-turning course in an abandoned warehouse in Melbourne, Australia, reaching speeds of up to 60 kmph - which can result in very, very expensive crashes.
The future is awesome.
