Hi, thanks a lot for the very nice features.
I am just slightly concerned that this PR adds quite a lot of boilerplate code which I am not sure is needed. I am also not sure why you felt the need of printing the lane identifiers, I don't really see the use for this and it also adds unnecessary complexity (per-lane identifier, font-size...).
Will approve subject to code quality improvements.

I think that passing around this additional return_last_pixel argument and the associated returned value is a bit awkward, it adds unnecessary complexity, requires changing the several functions signature (which are now inconsistent) etc.
Instead, you can just recompute the coordinate here: surface.vec2pix(lane.position(lane.length, 0))

I think this could be simplified, why is this list needed? is the y coordinate not just a linear function of the row index? maybe make this a lambda function.

Not sure why this is hardcoded, it doesn't seem to adapt to other configs. Also, this is not used here, please move to create_vehicles.

| # Walls |

not sure why the code for walls is that much longer, it used to be 2 loops for horizontal and vertical walls. Can you not just change the endpoints positions to adapt to number of rows?

I don't think you should edit these common files in abstract and graphics, instead just subclass the window_position() method in the environment to customise it.
Also, I don't understand why you use [0.5, 0.5] as a centre position, this is in meters so it looks like a strange choice to me.
Added the following enhancements to the parking environment:
2 rows with walls
4 rows
6 rows
6 rows all cars
Additional Obstacles
Random agent location
