water resistance is orders of magnitude higher than air, this is why irl, you can conceivably protect yourself from bullets by being submerged a short depth in water
Your physics knowledge is woefully inadequate; at 0.01% the speed of light, the difference between pushing through air and pushing through water are negligible. Both would be massively destructive to the ship and the medium traversed. TLJ shows us that the ship accelerates to near-lightspeed before going into hyperspace. Rogue One shows us you can go into hyperspace from within an atmosphere. The two together do not make sense.
