Street signs without exit, but in this mod, you can cross these signals, so you can discover new areas of the maps without exploring.
ATTENTION !! because there are undiscovered areas totally transitable, but in other places the road is cut and if you are not careful you can fall into the void.
The signs of street without exit, of blue color you can pass them, but the arrows of orange color that indicate that you can not continue by some exit of the highways, they CAN NOT happen and have collision. Attentive to the accelerator.
