Doors on cars today are essentially the same design our grandparents had on their Model T's and they bug me each time I open them in tight quarters and have to squeeze out sideways.
I had been toying with designing a really radical door design for years, but it looks like someone finally came up with an elegant design!
. . . Say hello to the future!
