Where We're Going, We Don't Need Roads

Ten seconds airborne in a rover. Gravity is the enemy, so cheat it: on Desolo or Novus (low gravity) drive fast off a tall mountain or cliff edge and you'll hang for ages. Rovers don't take fall damage, though your cargo may reshuffle itself on landing. On a heavier planet, carve a launch ramp up a mountainside with the terrain tool and hit it with speed.
