I'm going to go out on a limb here,and say suspect it got a little hot.er
Back in another lifetime when we lived in a free world,I used to just drive straight up the beach from NC to get to Va to shop for items not available locally. Been decades since the world was that free,but IIRC,it saved about 40 miles of extra driving if I had followed the roads.
Coming back home one day I spotted a brand new Series 1 Ford Bronch that still had dealer tags on it,being washed sidways by the ocean,and being pulled further out to sea with every wave. Both doors were open,and the panicky elderly owners who had just bought it that day to explore the wonders of the undeveloped ocean front were in a panic.
So we stopped,attached a tow rope to it,and pulled it out of the ocean for them. Once we got it up high on the beach I noticed the front hubs weren't locked and it was still in 2wd. When I asked the man why he hadn't just put it in 4 wheel drive and driven higher up the beach while he still could,his response was "Huh? I thought they automatically went into 4WD when it loses traction!".
You would THINK a Jeep salesman back then would have recognized the new buyer didn't know a damn thing about 4wd and given him a short class,but nope,he just took the signed contract and waved "Bye Bye" as this elderly couple drove off on their exciting new journey.
I somehow suspect it was traded in on a new car the next week,and a year later the new couple were wondering why the body was disappearing as it sat in their garage.
