I personally found that quite boring after the first 6 seconds, but of course I don't speak for anyone other than myself so maybe I'll soon be the only person in the world who doesn't find that remotely interesting as a spectator sport?
Part of the reason why micromouse is fascinating is not necessarily the "play-by-play" action, but rather the technological and mechanical skill that goes into running them so successfully - sort of like F1 being more engineering-focused than other forms of racing
From what I understand, F1 is about "emphasizing the importance of driver talent and creating a level playing field", hence the ban of tech like traction control. As an engineer, I'd love to see what the technology could do if unleashed. However, it's probably expensive and I doubt will catch the interest of anyone but uberNerds like me.
