The min and max anlgles indicate that the dial would be pointing between just below 45 degrees down and to the right to, by swinging left, a horizontal position. Is this upside down, or what? Also, if the minimum speed for the car is 120, then why do you initially set the speed of the car at ten? I will presume that only one car will be in the world at any time. If not, then you will other issues.
