The dune buggy scene is idiotic. That whole sequence could have been removed in favour of more character scenes.
I mean, I can almost accept starfleet making a wheeled vehicle (and from the sound of it, it ran on something more sophisticated than an internal combustion engine), so I am OKAY with it. BUT WHY THE HELL WOULD THE REMANS ALSO HAVE CARS?! That makes NO sense.
Hell, if the scene was deemed absolutely necessary (it's not), then give the Remans hover vehicles - at least that would've been something more exciting/dynamic/made sense.
