Turn signals

Have you ever sat in your car waiting for the left turn arrow to send you on your way? Have you ever, by chance, caught the view the turn signals of the cars behind or accross the intersection? The lights all blink at different rates! Okay, I can understand different makes of cars blinking at different rates, but I have seen the same make and model of car blinking at different rates! Madness!! Let me know what you think.

BTW, I am now faculty at Schaeffer Academy. A K-12 classical Christian school. I will be teaching Calculus, Geometry, Pre-Algebra and some other possibilities. Praise God.
