ATV NR6

Several movie scenes show the ATV NR6 moving from the ship to the domes at a faily high speed. However there is a sceme with David driving the ATV in the tunnels. Why was this not done more often? Granted there might have been a few tunnel details that were overlooked but still be able to transverse the tunnels at least to verify they are connectected to something important would have been a priority in my book. Sort of scout out the terrain before being consumed with detail. The Back to back seat design seemed awkward but I suspect this has been done before. It is kinda funny how the Engineer's head just happenned to fall out if the ATV when it hit the ship's ramp just before the storm. It was not clear to me how this happenned but the timeing was noticable, I have one final note about the ATV NR6 following the transport: It was always in the dust trails of the Personnel Carrier. Would it not have been safer to more to onhe side juust a bit for a cleawr view of the road ahead,, I doubt they would have hit a lot of traffic, It just seemed like the ATV path was in the worse possile plkace to travel safely toi the dome..or the ship. Perhaps the transportation posters would comment on this,
