Maybe it's just me, but it seems like more and more drivers on the roads are neglecting to signal when changing lanes or even when making turns. Sure, most the time it seems fairly innocent, if there are no cars around then what is the harm? Well, I'll tell you what the harm is. Sometimes there are cars or pedestrians around, and you don't realize it. And they are making decisions based on your actions. Bottom line is that somebody could get killed. The chances may be slim, but is it worth the risk? After all, it is such a difficult thing to do? Does it take a lot of physical or mental effort to move that little lever up or down an inch? There is no excuse for not signalling.
So do you know what I do? I honk at drivers who don't signal. Even if they aren't abruptly cutting me off, I honk. I encourage everyone to do the same. If we all start honking our horns when other fail to signal, these lazy and careless drivers will eventually get the message. If you help teach these drivers to use their turn signals, you might just save a life. So honk if they don't signal. Pass it on.
