it was rendered on i5 home workstation, 4K render took 6 gigs of RAM, yes, there is just one texture (but 4K) for road surface,
car body uses Blend material with 2 levels of glossy reflections on it, bridge uses Corona AO map in diffuse slot
empty steering wheel - yes! i tried to put a driver, but i no luck. i`m not good in charger driver rendering! :)
