The 'String' puzzle does rely on the object being (or very nearly being) a perfect circle, though. The outline of barriers round circuits is... not a perfect circle
Honestly, I find it surprising that we don't experience more breakages in cables and connectors across race weekends*. The guys that put them in are really very skilled indeed in making sure that they're situated in places where they're safe, but obviously some of them have to be in the line of fire and are at risk from an errant car (or marshal's boot).
*I remember the frequency with which UK broadcast TV used to go off air when I was rather younger than I am now, to which we always used to say "come on, put the plug back in"
