I pay money to ride on the bus and still see ads there.

“Premium lite”? What is this doublespeak?

When people have tried this they found you can’t just stay awake. Your brain ends up turning bits of itself off at a time, so while you can talk and move around you’re basically not fully conscious and will mix up words or not be able to move at the same time. They called it “microsleep”, and it’s the main reason why nobody tries to go for longer without sleep any more: beyond a certain point you’re not really awake or asleep.

Same in Edinburgh. The buses and trams have a capped fee per day but it doesn’t count if you’re coming from the airport for some reason…
