Agreed on trains. Train data hasn't been good historically so we only recently have the ability to improve this. Internal debate, but not sure we agree on more frequent options like tubes and buses. We're experimenting with real-time ETA, but its pretty whack, things could jump around, which may be ok for nerds but not normal people. Stay tuned, we're not in any way finished. This is what we work on.
