Sorry for the stupid question.

I've read on other threads that they love how BMW continued with the split tailgate design (like with Range Rovers).

But can someone explan to me why a split design is better than a single piece tailgate?

I figure with a split piece, even if I only open the top portion, loading things would require me to lift things higher to get it in and out.

With the lower portion down too. I have to reach more to get items deeper into the trunk. Plus I'll have to manually lift and close the lower portion.

The only benefit I can see, is sitting on the lower portion while tailgating at a game. Any other benefits?
