steer to the same driveline point, but to points slightly to
the left and right. The maximum variation is defined in
stk_config.xml (and should be between 0 and 1).
ATM THIS IS DISABLED! Since in my tests it appears that
the AI is not driving as good as previously anymore, i.e.
it drives more S-lines on straights etc. To enable this change
steering_variation in stk_config.xml
2) AI now handles multi-items better by waiting a certain amount
of time before using the next item.
