I'm sorry but this doesn't make sense to me.
Was it really a ditch or just a bump?
If it's the ditch they put on the side of rural roads, and she hit it at 40+ mph, she'd easily be in critical condition. I slid into a ditch because my tire hit the gravel, it was corn season and the corn was probably 3 feet tall, I the ditch at a shallow angle at 35 mph and it totaled my car and knocked me out for an hour until I called someone to help me.
I call bs unless you exaggerated somewhere.
