@Troggie my rage when the destination blind on the bus says "Sorry I'm not in service"
Some would say "Sorry I'm not in service at the moment" or I'm misremembering
just say "Not In Service" and stop assuming the waiting passengers want an anthropomorphic bus! or are literate!
@Troggie my favourite feature was a big (like, 3cm across) bright blue LED status light, on the dashboard of the bus, that was always on, to let you know the bus is a hybrid
the buses all have automatic gearboxes. the only difference from it being hybrid is the diesel motor shuts off when you stop and restarts when you exceed about 5mph
I used to carefully dismantle the light and put a speck of blu-tac on the surface-mount LED within to dim it. some colleagues would scrape the LED off its board completely
here's a frame from a video I took by putting my phone in my shirt pocket
