Luxury - in the city - is having no particular place to go, and no particular time to get there.
Put up your feet, but keep your brain engaged, and take random buses across the city on a psychogeographical drift. Bend the criss-crossing arteries and multi-coloured lines of fixed schedules to your will, and chase the setting sun.
If something - or someone - catches your eye, ring the bell and jump off at the next stop. Another bus will always be available to pick up the narrative.
You may not know where you are going, but you know where you'll end up. In a situationist playground, the bus is the merry-go-round.
