The stats and attribute of assets and drivers are just numbers. no where in the play it's going to be effective. Opponent with lower car assets and driver can easily beat you without any proper justification. This game works on random logic and luck. Developer of this game must have been high while developing this game. My drivers even after upgrading to level 8 drive the car like drunken monkies. Stupid game.waste of time . waste of money. Uninstalling with huge disappointment
