While looking at Doubledecker Trams for yesterdays Post, I found these honestly really cool looking Concepts for Doubledecker Trams for Stockholm! Thoughts?

The only reason I can think of for a double decker tram is for use on a busy route that needs to handle high passenger capacities. How is it then that in this case someone has somehow managed to design something with the most inefficient seating plan possible? It looks like design for designs sake, rather than for practicality or usability and completely unusable for anyone that needs access.
