Drones are perfect for the videogame-style 3rd-person chase view, which will be a hoot to see on the top rallycross championships.
The concept is simple: there’s an IR transmitter strip along the rear wing, and all the flying camera has to do is latch on to the transmitter in a distance such that it films just like a game in chase view. The camera can also be made to shoot live feeds. Because rallycross has short races, there’s minimal worry for battery life—after one race, just switch juice packs.
Unfortunately, it can only really be made to happen during qualifying, because who would want to see flying cameras bugging the race cars?
