First of all, thanks for sharing the link. I love idea of doors that fold/slide into the floor. That said I wonder 1) if Tesla's floor mounted batteries would take up the space this tech could conceivable use and 2) if Tesla's extremely high safety rating (https://news.ycombinator.com/item?id=6240862 https://news.ycombinator.com/item?id=6240862) would be impacted by this design (not to a degree that would lower safety beyond an average car, but not up to their high goals).
