I scoffed at the notion of drone racing. Then I watched this, and holy shit:
As a kid who grew up in the 90s, I remember the brief period when televised robot fights were actually a thing. Turns out that fighting robots in real life sounds a lot more exciting than it actually is, and so in modern times that sort of things is left to anime or the occasional mech movie (just watch "Pacific Rim").
Drone racing is kind of the opposite: it sounds like a really lame idea for a spectator sport, but is actually kinda cool when you give viewers the option to view a race from the first person perspective. The sense of speed approaches F-Zero levels of awesome, and the technology is getting better all the time. If head-mounted displays ever become ubiquitous, and if they can figure out a way to combat the issue of motion sickness, I think drone racing might have a chance at becoming a successful niche sport. Definitely beats Nascar racing, at least for me, but then again...I'm not from Tennessee.
