Such a point would be unstable; you'd only get stuck if you STARTED there, or ended up there while walking towards something else that for whatever reason you decided to stop walking towards and recalculate.
Also, if you're walking towards something, it makes sense to only look at the strongest of positive attractors--you pick something and go for it, you don't walk into the middle of two apple trees and expect to pick apples, you go for one or the other.
It's when you're walking AWAY from something that you really want to sum the negative attractors. If you're running away from three goblin siegers, you want to run in the direction that takes you most away from all three. If, on the other hand, you are surrounded on all sides by three kobolds, it makes sense to either be in the exact center, unable to move and cowering in fear, or else rush a perceived gap--both of which could happen with summed negative attraction vectors.
And if you really want to move, say, if you're surrounded by bowelves instead of kobolds and so staying where you are is certain death, then a random "jiggle" to pick a direction could help unstick someone who has at least one attractor/repulsor that should be causing movement, but who isn't otherwise moving.
