Tom Scott: Boarding planes could have been very different

Montreal has a few neat things like this. The mobile lounges (inspired by D.C.), the metro system that uses rubber tires (inspired by Paris), and the underground tunnel network connecting downtown (I think this one was original, and also inspired similar networks in other cities).

I feel like the spirit of techno-optimism must have shined a little brighter in Montreal for a few years, and so today we have this neat reminders of other ways that our cities could’ve been built. It’s a lovely place.

This is a really interesting concept. I'm a little surprised they haven't regained popularity with the budget airlines who prefer to avoid jet bridges. But then I guess it's still a lot cheaper to purchase and maintain using off the shelf buses and stairs.
