Okay, I like the idea of the shot. I saw that you had a lot of noise that's noticeable in the sky.
What I would suggest... Go back to the same spot, and bring a tripod (if ye got one). Set up and perhaps try and get a slightly higher vantage point to try and get more depth in the lights and less of the sky so that you're aiming down on the road a little bit more. Turn your ISO to between 100-400 and use Aperture priority and take the shot again. That way you'll have a better view of the lights, and it will eliminate some of the noise.
And another thing I might add is that the horizon is off... But it looks like you may be on an earthy slope. So it may require some careful tripod stationing to get the horizon level, but that would definitely add to the shot.
If possible try and keep the city lights in the right side of the frame. I think that would be a nice touch to see the headlights streaking toward the city, but that's just my personal taste I guess.
To the OP
i suggest getting more of the city into your frame, its a vital part of the picture and i dont think that having it cut off like that is helping anyone, and while youre at it, if its possible to disregard at least one of the two signs on the highway, that would also be benificiary(?) idk the word atm
To Plato
I didnt feel that that edit did a lot for the picture..
what aperture did you use and how long did you hold the shutter open?
ignoring the little details aforementioned, the most noticeable problem for me is that the oncoming headlights are more intense than the passing tails, causing your red streaks to be washed out and overexposed. that can be fixed by either going higher, as mentioned, or if that isn't possible, reduce your aperture. whenever I take these kinds of pictures, I get around f/22 aperture and at least 4-6 seconds shutter speed in ISO400.
