[MWForum]How to slow down a turtle/car travelling around a road network

[Tony Wilson]

That is a nice formulae you have there, Mike. I will start using it.
Do you know how Graham would get to stop the turtle (or car) when it hits one of the hidden turtles. Would you use 'when' and 'touching' and some sort of stop command?
