sadly, it probably will not end. The main contributing factor in crashes (i won't call them 'accidents' because they are all cause and effect) is either disrespect for others (impaired drivers, whether drink, drugs, or sleep have to get that way consciously) or an attitude of superiority (get your old car outa my BMW's way, you subspecies a$$hole, i'm in a hurry...), or momentary distraction with other traffic around (looking at the radio, picking up a fallen object, whacking a kid in the back seat, yapping on the cellphone...). Occasionally there are crashes from defective equipment in my area but not often because in order to get your annual license-plate renewed you have to have your car safety inspected.
The worst accident i ever saw with kids was on a winding 2-lane roadway where a drunk woman was sizzling down the canyon and hit a pickup full of boy scouts going up the canyon. Her momentum stopped the forward motion of the pickup and drove it 130' backwards, the topper on the truck self-destructed, the kids (12) were strained out through the openings and ended up strung out along the roadway and on the RR Tracks alongside the road.
Another bad one on that road was some jerk in a brand-new Buick that he had gone up to another state to pick up and was on his drunken way home. He hit a family head-on, killed the mom and dad in the other car and threaded the baby out through the front windshield where it hit the highway, probably dead, but got ran over by another car that could not stop. The drunk was sitting on the side of the road crying "My new car, my new car...". There were some truck drivers who stopped, and two of them had to restrain a third one from killing the drunk where he sat blubbering about his stinking new car. Then when i got there, they had to restrain me from whacking him also... or at least beating the crap out of him.
The crashes are not going to stop, as long as people are driving them in close proximity to each other. Of course, that's my pessimistic opinion, but it does not have to be true if everyone could relax and be polite. The guy who is speeding past everyone else is the same guy on down the highway who is two-inches off someone's bumper cussing for him to get off the road. And the beat goes on.
