Critique a statement that describes people standing on the side of the road and discuss why those people may be present.
"standing on the side of the road and staring at each other like idiots". That is really harsh. Did you know that when working on high power lines safety requirements dictate that there be a minimum of staff in case there is an emergency? A worker needs to be guided, sometimes by two people. But, there are times when they need to just be there "in case". 
And if someone gets electrocuted? Your description of people looking like idiots are trained emergency responderes for such an event. 
Try thinking of why those who look like "idiots"  are there.
