This is a thought that came up a while ago when I commuted. I realised that nowadays it's more space for the commuters standing and increased comfort for the commuters sitting.
The answer is simple. Standing and sitting commuters used to take a lot more space reading their newspapers and now everyone have changed reading position using their devices.
The last couple of days I have been observing people in Gothenburg, London and Barcelona standing and siting on planes, trains, trams, tubes and buses... My thought is now confirmed, there is more space and comfort in the world... thanks to online!
