One of my all-time biggest pet peeves is the failure to use a turn signal. That said, in today's tech-crazy world, I absolutely go bonkers when I notice people texting & driving. I have avoided FOUR accidents during the past year (two drivers who pulled out in front of me, one who ran a stop sign and another who swerved into my lane) and all of them had one thing in common: they were looking at / texting on their cell phones. I'm a naturally forgiving individual, but if a family member or myself were in an accident caused by some a$$hole who was texting/looking on their cellphone, I would probably pursue the harshest penalty against the culprit.
