Actually, since planet-sized objects are the only one's you'd have to
"stop" 
for, the sensor range that you use for your initial assumption is VERY 
suspect.  As for dodging, even against something with a velocity vector 
toward you, please remember that even if two vessels come within 1 MU of
each 
other they don't hit unless one is trying to ram (and maybe not even
then).	
I'd say that maximum "safe" speed is much greater than that shown.

On the other hand, it is refereshing to see someone trying to work this
stuff 
out by using factors other than the assumed maximum thrust capabilities
of 
the engines (I used to have to do these kind of equations all the time,
but 
factor in reaction time and the like--I'm in highway design and safety).
