that is 100%, not JRI because it was released a whole 3 years after that video IIRC. I do not think it is DRI either.
it is the pre remastered East coast USA. if you download an older version from steam you should be able to find it
I had a feeling it was ECUSA. A few months back I tried to bring old ECUSA to the new versions of beam but I had failed miserably.
I thought your second was Dry Rock island haha. But yes, It is definitely east coast USA. This video was made not long before I got the game in 2015. You can play a really old version by enabling older channels in steam. but I doubt the newer version of BeamNG will like ancient maps. Dry Rock Island for example works a little strangly
It's the early version of ECUSA no doubt that old map pack is this I think https://www.beamng.com/resources/revisited-2013-maps.554/
