I’d like to see a reckoning that takes the rotation of the earth into account, seeing what differences come of different terminal points (pole, equator, &c.). How quickly you get turned into a crayon against the sides of the tunnel, whether the tunnel actually needs to be curved to avoid this, whether the Coriolis effect matters, &c. My intuitions are probably wildly wrong.
