Upside down SUCKS! I’ve still got asphalt in My back from when a Sheriff hit us head on L/H headlight to L/H headlight and We flipped over and spun counterclockwise 300 yds down the hill when I was 15. That Crown Vic was much stouter than the Cortina We were in, We turned sideways when the L/F suspension hit the A post, the tyres caught and that put us on the roof.
I rolled a Chevy pickup when I was 15, went through the windshield about the time the pickup slammed head on into an embankment, then it proceeded to roll in such a way that it was facing back in the direction I had just come from, in that lane.
Walked away. Don’t recall any gravel. I had a few other minor injuries, but no gravel.
Thank goodness it was a rural road. No one else came up on it before the state police arrived. And no one else to blame it on but me - and road conditions. Icy gravel. Pickup was more than my little 15 yo mind and arms could handle once it started fishtailing. If I could have turned it one more time, would have driven off into the pasture.
