It bugged. When the game changed scenario in a blink i wasnt at an intended place, that led me to continue at the initial area, permiting me to wander through the map.
I saw many well constructed places, inside buildings too. I could appreciate some art there. Ive seen many buildings that in actual game you cant see... try deleting some stuff to make the playthrough smoother.
P.S. I loved those cars. Made me imagine a larger world, where you can drive the streets. I know it'd be a challenge. but maybe just a motorbike would make it very cool... smashing robots in the way...
