Most Taildraggers and long-nosed warbirds in particular have taxi visibility issues, and we have way to compensate.
Yes.
The problem comes when someone pops up in front of you unexpected, or queuing in a lane when the one in front brake and stop in without saying anything ..
There is no aviation methodology for a taxiing airplane to announce that it is slowing or stopping. Using a radio frequency for this would create communication chaos, and no one could know who is who anyway... "G-ABCD stopping!"... Is that the plane I'm taxiing behind?
It is simply the responsibility of a taxiing pilot to assure that the path is clear. If someone could pop up or stop in front of you, you should be aware of their presence before they could pose a collision hazard. Obviously, being the "pop up / sudden stop" pilot is not great airport etiquette, and courtesy would suggest the need to make one's self known, or give way to the moving airplane if practical, but it is a pilot's responsibility to taxi safely!
