What would be the best alternatives? I love Komoot’s maps for planning out MTB rides, and their Garmin app makes it super easy to navigate while riding.

To be fair, speed is relative. Imagine a plane flies at 500 km/h and is pursued by another plane at the same speed. If the first plane fires a rocket backwards that accelerates for a total of 200 km/h, then for an observer on the ground the rocket will still do 300 km/h, in the same direction as the planes. However, the guys in the second plane will see a rocket approaching them at 200 km/h.

Wind resistance, aerodynamics, etc. will have an impact, but it can work.

He also called them mûmakil in elvish. In my mind, when the Hobbits call them oliphaunts it is because a long time ago someone talked about elephants, and over the years the correct pronunciation was lost.
