Minimum turning circle

Well, this just defines, how sharp turns you can make at low speed. Here are some values again:

0.3 = Very tight. Use this just for fun.
0.5 = A bit tighter than average.
0.6 = A good average value.
0.8 = I use this for pick-ups and vans.
1.5 = This is for trucks, not very sharp turns with this value.
2.0 = If the driver doesn't have muscles to steer the steering wheel...
