Yosrit: The vehicle has LODs 0-4.
Maximum-Dev: Sorry, there is no extra sounds with the driving. I looked into it, and its so complex that I think it would require its own marketplace submission (which I may do one day along with damage, if theres any interest int that). But this package really just contains the base art with some standard functionality.
I just took a quick screen grab in UE4 of track assets. Basically its a few boarders/walls, track edging with front/end pieces for easy splining. Basic road geo with a shader that has a bunch of grunge and damage parameters. Also a few decals. The rest are just background props like advert banners, overpass, BG buildings etc.
