I'll offer an alternative and fully benign possibility.
Heavy rain. Super heavy. The driver goes across a puddle in the road and it either makes him slew sideways, or his brakes seem to have gotten wet/malfunction, or he has an electrical/battery malfunction of some sort after getting everything soaked by a puddle or a passing truck or something in the extremely heavy rain. Maybe headlights flicker or brakes are weird, or both.
Car not seeming right, he sees an oasis off the road, a fully lighted parking lot, and turns in. Switches off lights, in case a battery issue. Drives slowly. Switches back on lights to see what happens, and looks okay. Makes a lap slowly, stomping on brakes here and there to see what he gets (yes, this is seen as well). Eventually decides that everything seems okay, but he will stop for a few and let the rain let up a bit, and also let things drip dry a bit, before resuming. Turns off lights, sits for 3 minutes, decides it seems better, and he cautiously exits and goes on his way.
That's what I see.
