But remember that this is at the cost of having insufficient
(and needlessly expensive) buses to go around. SBS Transit does
away with such unnecessities for most of their buses, and the
result is that they are able to purchase more buses at a fraction
of the cost if they had brought in buses with EDS systems, which
translates into more buses to use for completely new routes or for
routes with higher demand (compare this with how A$$MRT rarely
start completely new bus routes (their "new" routes are often the
result of merging or seperating existing routes), while they
struggle to cope with existing demand).
Besides, side EDS display less information than placards, while the
front EDS often squeeze in too much unnecessary information, when
all we need to know is the bus number. Also, older EDSes are not
very visible at night.
Just to add: EDSes are also more likely to get spoilt, with dead
pixels and problems like that. You should see the front EDS of one
of the buses on route 963; there seems to be a problem with the
dots flipping over or something.
