I don't want to downgrade the experience you had in any way. It was horrible. But I think I know why people are judgemental about this issue.
In my own life, I've had many, many, smaller warnings. There have been moments where I was momentarily thinking about something else and I very NEARLY caused an accident. I LEARNED from those moments...at least, for a long time. Eventually, I'd have another close call and I would be careful again for a long time. If we are honest with ourselves, I believe we ALL get warned again and again.
Every time we see an accident while we are driving. That is a warning. Everytime we hear of a traffic death, that's a warning. Every time we pay our car insurance bill and complain about how high it is, that's another warning. Every time someone almost hits us, cuts us off, or runs us off the road into a shallow ditch, without injury and we can drive back out.... that's yet another warning.
Just how many warnings does a person need in this lifetime?
I'm sorry it happened to you and also thankful the person is okay. But it doesn't stop me from being MAD when people lose their lives because of .... DARE I SAY IT... STUPIDITY!!!
