WTF...is it really that f'in hard to use a turn signal. Sorry if your too busy talking on the phone or texting your loser friends, who only want to text you instead of ...what, actually talking to you with their own voice. Sorry if they're mute.. It takes zero energy to use a signal, so don't worry about losing all the calories you just gained eating that fast food sandwich or gulping down your 64 oz beverage you just bought at the gas station. Its simple, its courteous and gosh darn it, it might actually prevent an accident.
Also instead of realizing that you missed your turn and then slamming on your brakes and stopping all traffic...just drive down to the next turnaround, instead of killing us all...especially those on their cell phones and those who disregard that they are in a 2 ton vehicle that will kill. Have a nice day and treat others like you would like to be treated.
