If it can kill you it is critical. I had an intermittent short in the indicator switch on a motorcycle. One day it suddenly started indicating left at an intersection when I was going straight. A car in the opposite direction was turning (their) left and almost hit me. According to the other driver my bike started indicating (my) left as I neared the intersection so it looked entirely intentional. Fortunately we both had left ourselves safety margins and had eye contact so we didn't crash. But add youth, testosterone and aggressive driving and that could easily have been a really dangerous misunderstanding.
