Driving with 25 AI traffic vehicles in C1 Shuto Expressway is total CHAOS (I am using Ultra settings btw)! Just imagine how many vehicles that will crash into you or stop in the middle with no reason at any given moment, surprised that I didn't total the car in the middle of all of this! I suggest you to try surviving 56 km of derby starting from Tatsumi to Shibaura, really tests your driving versatility (I was doing all this with a keyboard btw)!
