Asteroid Collision

In uk.sci.astronomy Gareth Slee writted:
: Million to One chance of a collision apparently.
: http://news.bbc.co.uk/1/hi/uk/3200019.stm

from which:

"The chances of a catastrophe are likely to become even slimmer once more
measurements of the asteroid's orbit have been made."

If this is true, shouldn't astronomers increase the number of
measurements? If we look REALLY hard, we might be able to push it into
Jupiter.
Schrodinger had nothing on this one...
