This sounds cool, but I'm not sure why they couldn't just design it to always open with the tightest possible arc?

Dunno, but he showed the falcon door opening problem doesn't exist.

Climb over the front seat into the back seat or vice versa. I've had to do it before, when boxed in at a weird angle.

Since it's a suv I bet you could get out through the 2nd row. Would be a heck of a lot easier than opening a regular swinging door.

If there's space between the front seats you could get through that way.

Probably ask it to park itself.

As many of us know, it's still possible in many situations if you can get the front door open just enough to squeeze through. The reason why you want to engineer something better for the rear door is for families, mainly. You need a bigger aperture to help kids in and out of car seats, for example. That's a huge use case for the Model X.

If you have kids and you watched this you are going bonkers right now.

Normal doors do just as bad in those conditions. Falcon doors perhaps block better at the side and worse, obviously since there is a hole in the roof, at the center.
