Quickly fine-tuning opponent AI line float & speed values

If you want to quickly fine-tune opponent AI lines, you can use the interpolation function for AI line float points and speeds. To do so:

• Change to Virtual Road Point mode . You will see the AI line points (dark yellow asterisks) along side their opponent AI line float values (dark red Xs and lines)
• Hold Alt and click on the first AI float line point. Then hold Ctrl and Alt and click on the last AI float point you want to interpolate all the way with the first.
  
• Press Shift + Q to interpolate the AI points between the first and last points you selected as a curve; if you want a straighter line between the two points, press Shift + Alt + Q. If you want to recalculate the speeds between points as well, press Shift + S.
