I don't know... straight, I would assume, means that I could walk or drive a vehicle and not turn at all, ignoring any external influences like waves and currents in this case.

But your vehicle would itself "curve" "downwards" due to gravity, surely a straight line means that you can point a laser, or a hypothetical 0 mass particle beam, uninterrupted from your starting point to your destination.

Depends on your frame of reference. When traversing the surface of a globe, your described concept of a straight line isn’t intuitive.
