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
well, in shift+u you can choose follow car (hit space for the option) also, go to options-> veiws and near the middle bottom their will be a bunch of stuff you can play with to change veiw.
