I too am aghast when witnessing yo-yo's texting while driving/weaving down the road. That's an eventual Darwin list winner. Picture the headline!!
I would also point out that a daily issue that irks me is the lack of turn signal use by folks that can't spare the hand it would require to activate them. How many times have you been waiting to pull out, only to have the driver turn right at the intersection you are sitting at, and notice the phone to the ear?? This is a genuine issue for the hands free vs hand held debate. Yes, I know, some won't use them regardless.
Fact is there are MORONS out there, and those of us that drive with 100% of our attention focused on driving stand the best chance of arriving safely.
