Are you seriously unaware of how much work this would require to perfect? You can't just pop map data into a game and have it render a scene. Even laser scanning a track or a car produces raw data that has to have a lot of detailing to turn into a model the texture artists can paint on, the environment guys work with in the lighting engine, and then whatever else is necessary to produce a finished model the game can use. I do expect that PD are toiling away at something like this, but this particular tool may only work well on PS4. We'll see.
In any case, a bunch of people were supposedly expecting little or nothing they could use. And then when they get a few extra goodies, they still grump that the update isn't worthwhile. People are strange...
I like it, but may not be able to enjoy it till the weekend.
