To much of a snapshot to go over well in the challenge, IMO. A few thing that are distracting me. First is the sky, looks as if it has been selectively tuned up and doesn't look natural especially where it meets the tree line. Second, above the roof of the car on the right an obvious cloning job has been preformed. When cloning it needs to look natural. And third, everything (including the pavement) has a greenish hue. I wish you well in the challenge.
The funny thing is, whilst it might save fuel compared to another car, how much would it save if it didn't exist at all? The footprint from simply manufacturing a car is absolutely huge.
