My wife and the 2 kids (aged 3 and 12 weeks) decided to visit the wonderful US of A for the 4th long weekend. It sure was exciting.....
Driving south on I-5 just past Bellingham Wash, I was in the fast lane at about 70mph passing a pair of cars in the slow lane. Just as my front bumper reaches the slowest car's rear door, the S.O.B. decides to make a quick lane change. I tried to avoid him and ended up kicking the rear end out. All attempts of recovery did not work as my car ended up sliding back and forth until I did a 360 off the highway.
Thank goodness I didn't spin into the median as there was a wire fence divider and I missed a light pole on the right side by about 15 feet. I remember vividly as I hit the grass and slid about 100 feet, that I was praying "please don't hit anything, please don't hit anything". I ended up in a ditch with 8 foot high grass, wife and kids were okay, wife was freaked out, the 3 year old didn't seem to notice anything was wrong and the baby slept through the whole thing.
I got out of the car and a couple cars had stopped to check on me, but the offending driver continued on his way. What an Asshat. I called the state troopers and got towed out, damaged sustained; $177 tow fee and an exhaust packed with mud. The car drove fine after the "off", those e30's sure are tough.
I got away really really lucky. It could've ended up like this...

I really wish I had a dash cam...
