Is the garage driveway possible and somewhat practical for everyday use?

Hello,
due to structural conditions (slope, boundary, existing masonry), our current garage plan is as follows.
What do you think, is it "somewhat" easy to access with a small/mid-sized car (Polo, max. Golf)?
Reversing in would be easier and better, forward, hmm ...
And yes, this entrance option is not "optimal," but we currently do not see another solution.

The interior dimensions of the garage are planned to be 300 cm, door width 270 cm (max. 280).
Note: The access area ("maneuvering space") from the street to the garage is level.

(I have already built it to scale with paper, test with a real car in the parking lot is still pending)

Do you have a larger excerpt with property boundaries and so on? Maybe someone has alternative suggestions that you don't see yet.

The walls are the brown ones, right? Is there a reason why the right side is the way it is? So is that the property boundary? Or is there a possibility, for example, to curve something outwards or something similar?

The walls or non-drivable areas are the brown ones, on the right there is indeed the entrance to another garage, but it is flat and drivable (if necessary). The "critical" corner is the wall on the left, I have now marked the point in red/yellow. It is fixed (post, then wall). There are no "alternatives" except to rotate the garage 90° and place it "down" by the wall, but then it would be in front of the front door and the window (the wall is only 1m high and disturbs less).

Since neither the floor plan of the house (door possibly elsewhere) nor the exact height measurements etc. of the property are known, it is difficult to guess anything here. However, I fear that it will already be difficult to maneuver the car into the garage. Take a slight diagonal through the 440 cm long car .. then you quickly reach 500 cm.

The exciting question is also: Will it always remain a Polo/Golf or something similar? Do I want to choose cars in the future based on whether I can still maneuver them into the garage? I would rather plan differently now and keep options open for that.

Backing in would be easier and better, forward, hm ...

if you are parked inside backwards, you need the space to open the door and block a door to the house entrance, plus the trunk is hard to access in the corner,
so drive in forward, and the trunk is accessible at the garage door.
It is a narrow driveway for Polo/Golf class, consider they are also getting longer and wider.
If possible, move the garage one meter back, that would ease the situation.
