I went back and looked at the newsletter e-mail. Of course, they do have disclaimers that they do "not show the final configuration or quality. Many aspects, such as brightness, light origins and other aspects are all still in-development" I noticed the disclaimers after looking more closely at (and enlarging) the early alpha screenshots.
In the first shot, the lights are ostensibly streetlights, although all that can be seen are the poles, and not the actual points of light. The poles just seem to end. So, are the light pools coming "forward" from point sources that aren't actually there? Between each light pool are black "V" shaped dashed lines of unknown origin. The only object that is maybe receiving light from these light pools is a single car, which is actually under a gas station roof, so unclear on how things will be lit in these pools, but undoubtedly better than current, which is not at all.
In the second photo, the "forward" headlights are lighting well down the track to the edge of the photo, lighting the track and the ground quite well, but doesn't it already do that? But the reverse light, while it appears to be lit, does not seem to be lighting any track in that direction, so still unclear to me how this is going to work.
