Here is some incredible technology. I'm not sure why it hasn't found it's way to the mainstream auto industry, but it sure would cool. Invisible car doors. The doors of the car actually slide down and under the car, similar to rolling a window down. The whole door disappears. You will notice in the video, people trying to get into cars parked close together can still do so because there is no door to have to open.

This would be a wonderful reality!
