It's a good start, however, 'Smooth' mesh doesnt correct the small roads. 'Bumpy' is excessive. Track is about 0.5 to 1 car width to narrow in places. The 'back streets' section is almost undriveable with pretty much Cliff drop effects in the road... Needs work, The ground textures out of T2 for example looks like mud...
Overall, good start given that we have no Nashville Street otherwise... but needs work
