It isn't just near collisions. I was once stuck be a car with enough force that it bent my bike frame, ripped the mirror off of their car, and created a crashing sound loud enough for people to hear inside their homes. As far as I can tell, the motorist never even slowed down. The people who came to my aid were nearby residents and pedestrians. How I managed to walk away from that one with little more than (nasty) bruises is a mystery.
Other times attentive drivers exhibit attitudes that are less than redeeming. I once flipped on some streetcar tracks. Attentive motorists simply drove around me and went on their way. The people who did check up on my condition were pedestrians.
I've had a number of other experiences in my life that leave me feeling as though people cease to be human as soon as they get behind the wheel of a car. While there are exceptions, they are exceedingly rare. Getting back to the article, I am extremely worried about children being on their own on the streets. It isn't because of those who would intentionally harm them, since that is relatively uncommon. It is because very few people behind the wheel even seem to care.
