it is close to its target. This gives karts a chance
to escape a rubber ball by driving irretically.
Also added some debug output to indicate when the
ball lost sight of its target (i.e. the ball was
going directly to a target, but then the target
was suddenly too far away), so perhaps the ball
should be removed then?
ATM the ball will continue, trying again to hit
the leader in the next round.
