Google has just added public transport directions for the whole of London. The London Underground alone has 270 stations. If that's possible, why are we still largely stuck with no directions on Google Maps in Australia's major cities?The answer has nothing to do with technology, sadly, and everything to do with recalcitrant state governments doing a lousy job of making their timetable data openly available for use on Google Maps (and in mobile phone apps and lots of other services). It has happened in Perth and Adelaide, so it clearly isn't impossible.
Commuters have a messy enough time of it as it is, and making this data available is a straightforward task compared to dealing with overcrowding, ageing rail networks, bad weather and everything else. So just get on it with it government guys, please!
