Or it might be like the Ridgeline's trunk. For those of us who use the trunk often, we can't imagine living without it. For Brand X truck owners, the Ridgeline's trunk likely seems like a useless curiosity.Might be one of those features that sounds innovative but not used much...but gets the attention of buyers.
I have an old friend who has a band, and he hangs onto his Avalanche in part because he can cram so much band gear in there under his tonneau cover/into the cab.
Same could be said for the Ridgeline's side-opening tailgate. I imagine most non-owners don't realize how much easier it is to load and unload cargo when the tailgate isn't in the way.
It will ultimately depend on the user's habits.
