Yeah, I'm talking to you. The same twit who can't move a finger half an inch to their left and flick the turn signal mechanism either up or down to indicate which way you might be going next while I'm forced to sit behind you and guess. I know, I know -- it's really hard to drive AND operate the finer points of the vehicle at the same time. Remind me not to get near you on the road when it rains, since you won't be able to see where you're going owing to your lack of ability to turn on the windshield wipers. What's odd though, is that you seem to have little or no trouble changing your radio station, or handing your kids stuff from your bag in the front seat to where they sit in the backseat, or yammering away on your cell phone while steering with just the one hand.
And I also love it when you're on the highway, doing 70 miles per hour, and I'm supposed to know you want to get into my lane based solely upon the fact that you're swivelling your head in my general direction. Sorry, man, I don't do head signals with complete strangers. I need your turn signal, and then, if, and only if, I'm in a position to do so, will I slow my own car down and let you in. Please re-read your drivers ed manual (they are free at the DMV) and attempt to comphrehend the part that says I am under NO obligation to let you in, especially if doing so will cause me to operate my motor vehicle in an unsafe manner.
And it goes without saying that there comes a point where you just shouldn't even bother with your turn signal -- like AFTER you've already swerved into my land and cut me off, or when you're halfway around the turn. At that point, it's just too damn late.
But if you weren't such a fucking jackass, you'd know that already.
