It’s hard to see from this partial screenshot, but the getaway car has reversed direction after hitting the road block. The road blocks are temporary and disappear after some time, and you place them by pressing the space bar.
Only six hours left to go. I still want the getaway car to rob banks, make turning decisions to avoid road blocks and the player’s car, and, you know, get away. Oh, and I need to put roads back into the game. B-)
