Accidents... which by definition... are not done on purpose, don't happen on roads?
This is an awful tragedy, and completely avoidable. This situation was not an "accident" in any way.
But this post is absolute nonsense. Sure, some accidents happen because of things you said. A LOT of accidents happen for many other reasons outside of someone's choices and recklessness.
Car blows a tire and swerves into another car... accident. Car hits a patch of black ice and slides into a concrete wall or another car... accident. I've had it happen more times than I can count where I've checked my blind spot and it's clear, so I've gone to change lanes on like a highway/tollway/interstate, and someone else changes lanes from the far right lane into the same middle lane I'm trying to change into, and we almost get in an accident. I've seen this happen where the cars do actually get into an accident on account of it. Car has to swerve to miss an animal that runs out, hits another car... accident. None of these things are on account of recklessness. They're... by definition... accidents.
Plenty of accidents happen involving people driving in a "safe and responsible manner."
Maybe you should clarify your post by saying something like "Drunk driving accidents aren't "accidents."
