Just after the bridge after crossing the finish line on the left... see pic... (on the road, left under the mirror)

it looks like a crack in the road really. i just looked at it ingame, the one parts higher than the other by a bit. all citys have cracks in the road, and well, all those bumps in south city are what..make it a city

imo it should stay their

meh IMO, more cracks! pothpoles lol
