Those doors would need a ton of space between the vehicle and the door though.

They fold outwards, and would require less room anywhere inside the garage, Han the op version.

Well, the video I saw at the link provided showed the doors opening inward. If they normally open outwards then it obviously wouldn't have any additional clearance requirement on the inside of the garage.

EDIT: I stand corrected. I went back and looked at the image (not video) I saw before. It was deceiving due to the layout but it was folding to the exterior. http://www.bifold.com/assets/slider-37.jpg

I think he means a vehicle parked in front of the garage door.

Some of these designed wouldn't work in places like San Francisco if you own a vehicle that just barely fits into said garage. The entire interior/exterior operating clearance would need to be available and measured carefully.
