Thanks for the warm welcome and vote of confidence Larry.

The point is, that maybe some people , and maybe you're included in this
group, should not just blindly assume that because something is written in
a book that is is almighty and the absolute very best way to do things.
I offered a logical approach that made sense to me to be a much more
effective catchall for runway incursion type accidents.
Newps, demonstrating his clear understanding of both sound logic and in
depth knowledge of the regulations as well as real life operations has shed
light on how it works in the real world. So it seems clear to me that
there's always a compromise , if you do things the absolute safest way ,
you lose a lot in terms of delays and inefficient use of time. but if you
are too loose with the regs , then you start having more accidents
statistically. So the FAA has come up with what is probably the best
balance between the two to keep us moving and keep the potential for
accidents at a low level. So the way things are , I can see sequences of
several things that come together which would still cause an accident. for
example, the pilot in the light aircraft leans for taxi and accidently
stalls the engine on the runway at the same time the heavy with a newbie
first officer has a checklist problem that gets the captain funbling around
the panel as he starts the roll and the tower controller spills his coffee.
etc. etc. My proposal would probably keep us away from accidents caused by
this scenario , but , it would also slow us down greatly in day to day
normal operations.... so we have to decide after crunching some numbers
that the probability chance that all these bad things will come together for
an accident does not balance the benefit we get on a regular basis. So I
guess the moral of the story is that the law of large numbers says that
given enough time there WILL be accidents caused by various different
scenarios like the one I described above so PAY ATTENTION to what you're
doing at all times.

I'm not sure what the regulations technically say

Then perhaps you might consider looking up the appropriate
regulation/order instead of admitting your ignorance publicly in an a
worldwide forum.
