As for inside displays, since GPS/AVL is to be fitted to buses, it'd be
relatively easy to add a bunch of features inside:

For passengers, a display with:
- Bus number & destination.
- Clock with exact time
- Next stop display/voice announcement.
- Messages from TfL / bus company
- Messages from advertisers, or other entertainment

I have seen buses with accurate clocks in them, and ones with
advertising screens on the upper deck (usually used to show what the
CCTV is seeing, but occasionally used for advertisers). As for
messages, the only ones the buses seem capable of saying is "Bus
stopping at next bus stop; please stand well clear of doors", as though
we were all pillocks!
