Okay - I haven't looked at any of the other answers... I'm just looking at the picture...

Oldish car (200k miles on it) with a full tank of gas. Windshield might need cleaning, though that's less likely if the driver just left a gas station.

40 mph, low revs, so a lowish gear, probably 3rd gear, dropped a bit for the curve ahead. Radio on, but not too much volume. Not likely to be a traffic report though.

Driving on the right, American lane markings... in the countryside somewhere, steep bank on the right, lower on the left, perhaps a river to that side. This is made more likely by the possible swarm of moths coming from that direction. (or is that dust on the windshield?)

Of particular interest is the glowing object up ahead. I think it's just a reflector on a post to show the direction of the curve ahead (which bends softly enough to be completely manageable at 40, even if you're unfamiliar with the road.) However, the glow could also be a deer ready to jump across the road - and they are rarely alone, so I would consider slowing down a bit further due to the possibility of there being deer - at least until I could be certain what that object was.

We are at twilight (or early dawn), so if there are deer in the area, they are of greatest risk about now.

The sky is clear.
The woods are deciduous and some trees are not fully-leaved, so it's late spring, I think. I would suggest this photo is likely to have been taken somewhere in the midwest of the US - south of the line of the pines and evergreens, but north enough to have a distinct set of seasons.

Oh, there's also some sort of pull off to the left, perfect for a weary driver or a carsick child... (or someone who can't make it to the rest area!!)

I think that's all I'm going to give you this time.

Fun challenge - maybe I should see what others have said now.
