I just remebered I meant to mention this the other day. LOL
Blinkers (aka turn signals, directionals) are not optional. They are not some nifty little gadget they included with your car that you only use if you feel like it. Their use is part of the rules of the road/law for driving a vehicle. Really, it's not hard to use them. Stop being so damn lazy! Oh, and they're meant for ADVANCE warning of turning. If you decide to use the blinker at the moment you're about to turn you're too late and you've missed the point of the blinker. I can figure out you're going to turn! Likewise, if you get into a turning lane first.
And one more thing - just because you flipped on your blinker doesn't mean it gives you an automatic pass to come over in someone's lane. Flicking it on and then immediately pulling over in front of traffic is NOT okay.
What's so hard to understand?
