Ah, yes, sand and cars (that aren't beasts with big crampon wheels and 4x4 drive) don't go together.
Once, in Greece, I started to park my car in an improvised parking lot that was sandy and after 5 minutes of trying to get out of the holes that my wheels had deepened, I had to call other drivers for help...
Fuck it, I didn't have a shovel and some thicker longer boards in the car, I headed to the beach.

Also in Greece, on a sand bar near the town of Posidi, which extends about 1 km into the sea, I witnessed several times when inexperienced drivers got stuck in the middle of the bar and then had to pay for towing.
Taught by the experience of getting stuck in a parking lot, I only drive on hard surfaces, I don't go in the sand.
