I don't even understand now that's physically possible without a forklift. Getting the wheels stuck: sure.
I'm guessing front right wheel went into the ditch, lowered the bumper enough to bite into it, and momentum did the rest.
A new type of pit maneuver, likely helped along by where the ditch has concrete sitting just before. Truly an inexplicable confluence of events. But I can see it now.
To be fair this is terrible road design.
Maybe it's in Russia.
It is an old Soviet design. Many countries in the old Soviet block states have this. I just about did a one legger down them a couple times in Uzbekistan.
saves so much space!
