Why do we indicate when we drive? Some infer the person in front of me indicating means I don’t need to; it’s a short turn no need, or there are lots of cars I’d better indicate.
The interesting thing is indicators aren’t for us. They’re for others, we know where we’re going.
Except when we perceive a high risk, we will definitely indicate. This is where I’m going. Please don’t hit me.
That’s like a lot of things, if we think things are high risk (or stressful) we will panic a bit, make sure people know what we’re doing. If it’s low risk we’ll let things slide. However it’s when things are carefree that you probably need to indicate.
