It's really surprising to me that mattresses larger than a king/cal king are not more common. When I was single and sleeping on a full size mattress, that felt pretty good. Now that I have a partner and we upgraded to a king, I actually have LESS space since there are two of us sleeping in a bigger mattress. A king split between two people means that each person has the width of a twin size mattress. In my opinion, this is entirely inadequate and is a massive downgrade to me. A full size mattress is 54" wide, so for each person to get the equivalent of a full, you'd need a mattress that's 108" wide (Alaskan King size.)

Public transit doesn't suck, but the biggest problem as you say is that it fails to solve the last mile. Public transit is incredible if you live very close to the designated routes. For now.

Once cars are fully autonomous and become cheaper, faster, and more efficient than current forms of public transportation, current low speed trains and buses will become unused and obsolete. Except for the hyperloop and air travel, I see any investment in public transit infrastructure (trains, buses, subways - hell even parking lots!) to be a complete waste of money. In the 10 years it would take to build a new train through a city, cars will make it completely useless.
