Airplane taxiing is manual. ATC can tell the plane to use runway A, and the plane can check that A is free, but neither will stop the pilot from accidentally steering into runway B.


There’s nothing preventing airplanes from knowing the coordinates of every runway in the world and working out the truth using GPS though.


This would elevate the impact of GPS spoofing from a minor or major [1] nuisance to a significant terrorism threat.

Only if you rely on it for your positioning 100%. Presumably none of the existing measures would change.


Modern passenger airplanes absolutely do have runway maps.
