So you would rather that your family fall on financial hardship due to lack of income than to claim against insurance that is paid for for this very purpose?
You're not attacking her personally, and it's not about "revenge" or "punishing her" or whatever, which is what a lot of the posters here seem to feel; looking at it in a purely logical and practical way leaves only one appropriate course of action - if the injury is going to cost you (loss of earnings/medical bills/etc) then claim for it.
Just out of curiosity, would people feel different if she had accidentally driven into the OP's home when parking in the driveway and caused major structural damage to it?
But we aren't talking about a house or a car, I don't think anyone disputes the fact that the insurance is there to pay for damages to the car or a house etc. It's about people.
I understand what you are saying however this is exactly why I said it's complicated. Because everything you said was a perfectly valid consideration.
But the fact is, a lot of people will not look at the situation as only a series of numbers and facts. I do have the ability to do that of course ...but I don't necessarily agree with the system such that it is. Not that this should change anyone else's point of view, it does influence my own of course.
I also don't see any issue with meeting the costs of the accident, including lost earnings of course, but it seems to me that some people seem to go beyond that, they expect a monetary payment purely for 'inconvenience' an amount of money that someone decides is enough to make the whole ordeal 'ok' ...this goes beyond just replacing or fixing what was broken and meeting all the necessary costs. And this is where the line needs to be drawn in my opinion.
I did once, over 10 years ago cause damage to the front of my mother's house when preparing to pull off the drive (I was learning to drive at the time, in my grandfather's car), my first mistake was putting the car in 1st rather than reverse gear, as the car surged forward I realised what I had done but was too inexperienced to immediately correct the mistake as I panicked ...thus I caved the wall under one of the front windows in. It wasn't exactly major structural damage but it was bad enough considering I did it from a standing start about 4 feet away. Anyway I paid for the damage out of my own pocket, it was my fault and I accepted responsibility for it. I know this is not the same situation at all, but I would not have resorted to insurance unless I felt it was necessary. Which incidentally is part of my point, does the op feel that it is necessary? ...does his wife concur ? ...because too many people do make too many unnecessary claims ...and when family is involved that seems rather ...uncalled for if it isn't necessary.
The whole reason I said at the end of my post that it was a rather complicated situation is because of all of the considerations you mention ...and more. I can argue with myself about it even, I could justify either viewpoint as being perfectly acceptable to myself. But, as I said, the law makes it seem more simple than I feel that it really is ...which is exactly what you have done too.
