Main differences in that gif are:
Chase camera is farther away, so the car seems less detailed (either lack of pixels or a different LOD) and the FOV is also different, so that the proportions of the car make it looks like a toy.
Different TOD (time of day) setting. Rain is not present so there aren't road reflections and fog is not there. We don't know if they chose a specific TOD for older trailer making everything was perfect while the most recent gameplay fragment with a random TOD, so less impressive.
Within the light beam of the helicopter all interaction with the other light sources is removed.
Both scenes have cubemap reflections in the car, but most recent scene show them only in the front of the car, maybe because that problematic helicopter light interaction.
And the most important thing, when player select an object to interact (to hack it), that object is painted white on the screen. In this scene, all the bridge is selected to be hacked, and the white effect crush every detail over the bridge. A good solution for that problem is to create a small panel in every end of the bridge being it the object to hack in order to move the bridge.
The rest of the gameplay show a similar quality than older trailers. Grass and shrubbery don't cast shadows but we barely see any of them before. First reveal has a lot of dynamic assets on screen, and big decal diversity. This only can be there (in a big open city) for specific zones during a mission or in a small high densitity zone packed for a trailer. When used TOD has a bit of rain, every surface had a great specular effect in older trailers, but we can't see rain in new gameplay, so we can't draw conclusions as will be the visual downgrade in rain or nighttime scenes.
On top of that, there are another problem with multiplatforms games; they don't have a loyal fanbase that defend them for whatever reason against any criticism.
I think people are too suggestible and fall into fashions where it is easier to follow the flow. There are even people who say they have low poly density characters, lol.
That car does look like it's floating above the road though
