They’re only on the screen for a fraction of a second, but note the two very steep ramps by the left side of the street as the driver enters the parking lot. I don’t anticipate anyone driving their car up one of those – the arc is so steep that the car will bottom out.
On closer look I’d bet it’s a “test drive” ramp for VW AWD vehicles. Jeep does something similar at auto shows to show off their vehicle’s offroad capabilities.
There’s a gate at either end so ‘regulars’ can’t get there & there’s even a set of baby bumps at the far end. Given what I’ve seen elsewhere, I do believe you’re correct in that they are low-speed “look what our car can handle” test ramps
This is my guess too. I see some sort of “park the car elevated nose up” displays in a few dealerships near me, but nothing like this steep. I would bet one car parked nose up on each side
