How many things can you think of that you used to see when you travelled by bus or coach in the UK that you don't see today?
Here's a few:
Conductors (AFAIK only London still has them now, and only on the 15H heritage Routemaster route and on "Borismaster" operated routes)
Open rear platform buses (again apart from on London route 15H and "Borismasters", although the latter also have front and centre doors)
Mechanically operated ticket machines, both of the conductor and driver operated variety
"Pendomatic" change-giving chutes
Buses with centre exit doors (AFAIK only London still has them; everywhere else uses the front door for both entrance and exit)
Buses with three- or four-leaf doors
Step-entrance buses (as opposed to low-floor which is now the norm just about everywhere)
Yellow front entrance doors on London buses
Tickets with a letter to denote your fare on London buses
Entrance turnstiles on London buses where you could pay your fare instead of paying the driver
Clippercards and Clippercard validators on Manchester buses
Smoking allowed on the top deck of double deckers (I think it was officially restricted to the rearmost seats by the 1970s or '80s, when at least in London buses had signs at the front saying smokers are asked to occupy rear seats, but this rule was often ignored) and in the rearmost seats on single deckers
