MEGA late reply, but while I certainly agree that BeamNG would greatly benefit from support for larger resolution/streaming/tiling/multiple terrains, BeamNG is in the unique position in that it's both open world, and features multiple maps. Most every open world game in the last decade has had one map, and nearly every game released in that time that has had multiple unique maps has been linear/track-based. Bigger maps are still on my wishlist, of course. But if you're looking for examples of recent games to use as a precedent, pickings are going to be a little bit slim.
Oh, your not late, I posted four months after the last reply. --- Post updated --- Only some mods, and a beefy computer, have enough room in a map to even be called "open world".
yes, this! we really need a 'delay' function, for older car with bulb type lights, as they don't instantly come on like LEDs do seems like something not too hard to implement and would add that extra bit of authenticity
