Plain and simple, a huge factor is distracted drivers and pedestrians who are too busy texting and/or listening to music to even give a shit of their surroundings. Automakers are making vehicles more and more interactive increasing driver's distractions plus adding all these so called safety features into the vehicles makes an already poor skilled driver, even worst. Police are not enforcing the laws enough, fines for texting/talking on your device (IMO) are no where near strict enough.
