Re: Has the author not heard of TFLs Live Bus Arrivals?
"Oddly enough, the system will append the characters "LF" to the time to tell you if the bus has a low floor for wheelchair users."
IINM, THAT flag can't be helped because of disability accommodation laws. In America, we have the Americans with Disabilities Act. I believe England has something of the like.
Have you tried telling the bus people to adapt existing parts of the SMS to multitask. The only way they can REALLY be out of letters is if all SMS-valid characters for the entire length of the text is spoken for. Under those conditions, I don't think they can REALLY say that, and I would think they can find SOME way to cram in more indicators in existing text locations.
