Well, that about sums up this post.
Holy Christ, people. Is it possible for me to drive anywhere these days without being intercepted by at least ten individuals that have no idea what a goddamn turn signal is? Or even how to use it? It is literally one of the most important actions you perform while driving, next to staying awake and keeping both hands on the wheel. And it's not even that hard! All you do is flick the little lever up or down! It even does half the work for you and returns to its equilibrium once the car is done turning.
To illustrate how simple it is to initiate the turn signal, I've taken the liberty of "drawing" some instructions for people who lack the capability of understanding the concept... oh, shit... flaw in that plan. How can I expect them to "work the computer machine and the interwebz" if they don't know how to signal? Hmmm...
