This isn’t an actual “parking lot” as people are thinking, it’s an inventory lot at a car plant/dealership.
And the reason why it’s not an actual parking lot, is because it requires everything to be too perfect to function.
If a car is too wide, it’s not able to drive through. If it’s too long, the back will hang out and stop any other cars getting passed. If you park too far forward, you can no longer use the other carpark in front. And because everything is such a tight fit, many people are going to find it very difficult to park, especially when you can’t see the corners of your car.
