whilst it looks very nice and will look even better to indiscriminate vidgame players, there are some rendering errors in joepub's first img in this thread:

• car shadows are neutral grey (r=g=b) even tho the scene appears to have a blue sky
• car shadows are not motion-blurred
• sides of cars don't reflect anything
• guard rail/barrier casts no shadow
• spectators cast no shadows

since this means there's no GI nor proper reflection/shadow calculations, even poser 6 or 7 could do a better job of it IMVHO.
