"Breaking the spell" of Bystander effect???

So follow me on this one… “Bystander effect” where something happens & people stand around and watch…or worse Video a drowning person for their youtube channel.
Sunday I was headed home up McMullen Booth when all the traffic in my lane slows to a dead crawl & gets all swervie up ahead…when I finally get up there there is a Damn BOX SPRING off a King or Queen size bead laying across the lane! No body is doing anything accept trying to get around it. I stop & dive out to grab it, and suddenly the guy behind me does the same thing. We grab it together, toss it in the grass, & take off.
So…did my stopping “Break the spell” of Bystander effect? This is not the first time this has happened to me, just the first time I’ve realized it fully that people act after I do. Has this happened to any of you? does this make what we do actually more important? Opinions? Thoughts?
