Why do so many drivers have trouble with using their turn signals?

What do face masks, turn signals and condoms all have in common? If you don’t use them as intended they don’t work. The name is a giveaway. When you intend to “turn” you “signal” to communicate with other drivers. You don’t signal after you turn, as some do, you don’t start signalling as you are turning, you signal before you turn or change lanes.
