I don't know about you folks, but personally the way that doors on cars are designed today is something that has bothered me for years.
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!
