My pet peeve: Cogs that would not function as a symbol of good process

There is often an unnecessary disjoint between what a company does and the graphics they use. This poster for Brake Engineering is meant to emphasis their meticulous process and the quality of their parts.  Illustrated by a line of cogs that would not actually function by successfully transferring movement in the first cog to movement in the last cog in the line.  Which rather undermines the message. Bad cogs are a real pet peeve of mine.  It would have been just as easy and far more effective to illustrate a system that would actually work.
