this makes it worse on some other tracks (xr591, zen).
Maybe we should tweak AI per track?

// tight corners. In some cases it would need a reasonable large 'lookahead'
// to know that at a certain spot a zipper or skidding should not be used

// (star_positions-end_positions). So a gain of -10 means that basically
// the new AI fell from start positions 2,4,6,8 to end positions 6,7,8,9.
// On the other hand, +10 means the new AI took positions 1,2,3,4.
