GG,
So very, very sorry to read this. When I saw the title and that you were the original poster, my heart sank.
Although we've never met in person, I feel quite a kinship to you--we both have the same alma mater, both got our cars at almost the same time, have both been active on this forum for many years, and now have both gone through the experience of losing our awesome cars....and within 2 months of each other, no less.
First and most importantly, I am glad to hear that you and your son are ok. Although my sons were not in my car at the time of my accident, I remember hugging both of them and my wife very tightly after I got home. We are lucky to have been driving a tank. Keep forward-most in your mind that things could have been much, much worse.
I can also relate to the feeling you likely have right now that yesterday feels like a dream. You might be kept up at night, reliving those moments, wishing if and wondering how things could have been different. But in the end, you and your son came through unscathed, and that is by far the most important thing of all.
Although it sounds like you have a few medical hoops to jump through, take heart that you WILL be in a Model S again.
I have recently gone through the process with the insurance company and all of that--so if you need advice or have any questions about any of this, just PM me.
One more thing: less than 2 months ago, I was sitting in a wrecked Model S, off in the trees by the side of the road. Although there was initial heartbreak, it will soon pass when it really sinks in that, as cool as it is, your car was really just a heap of metal and plastic that can and will be replaced.
Take a look at my signature. i'm confident that before to long, yours will have something similar. Once you handle the medical concerns, you can look at this as an opportunity to upgrade/modernize. You already have your wife's support, after all.
Again, very sorry to hear of your accident, very happy to hear everyone is ok, and I'm looking forward to the stories about your new 85 once it arrives.
Todd
