I agree. An LED display would have to be *very* high resolution to
even approach the legibility of a blind.

All the same, there is no reason not to have the technology _inside_ the
buses. But then, London Transport and its successors always have been
several years behind the times - the sign which lights up when someone
presses the bell to request the next stop was in use in buses in Paris
in the early 1970s, and probably before, while they did not come into
use in London until the 1980s (I remember thinking "What a good idea!"
when I first saw the signs in Paris buses). And advertising/display
screens are only just coming into a few London buses now - they've been
in Paris ones for several years!
