Wow, really glad to hear that your wife, and everyone else is ok!
The big guy in the clouds was definitely watchin over her..
Something similar happened to our family about 10 years ago. We were on our way to the grandparents house which was in the country. All six of our family were in the one car, an XF Falcon station wagon. I was in the middle bench seat in between my mum and dad as I was the youngest. Anyway we were travelling along at 100km/ph when a car decided to pull out in front of us. There wasn't enough time to brake and we were heading right towards the other drivers door. Luckily my dad had the reactions to swerve to the left slightly and hit the rear passenger door. Their car span around a few times, as did ours. We both settled in a ditch. Un-believably no one was seriously injured. Considering there was 6 people in our little car I am amazed we all survived. And if my dad didn't swerve that little bit we would have killed the other guy. I was only 5 at the time so I wasn't entirely sure what was going on. I wanted to do it again! :P
