I may be missing the point here, but it looks to me like you're trying to reinvent the stopwatch. As running something automatically in the background seems to have too many complications, what about a service that you activate when you get on a bus and deactivate when you get off? If you want to fancy it up, you could make it show bus stops within 50m and let you select the one you are at when you get on, and again when you get off. Make it really fancy and let it figure out which bus you took if you like, but that can always simply be entered in. If it records the time between you pushing "I'm on the bus" and "I got off the bus", then uploads it to your database don't you have what you need?

Thanks,
Rustam

A GPS in a car has its sensor stuck inside the windscreen, pointing at the

But that to me isn't the biggest problem. Turning on the GPS on either an
  iPhone or an Android handset is the fastest way to guarantee that you'll
  be staring out of the windows on the way home, because your battery will
  be flat. Even when I need to use the GPS for my own benefit, I try to keep
  the sessions as short as possible so that there's a chance my battery will
  last through the day. The idea of installing an app that I just leave
  running in case I get on a bus that's constantly accessing the GPS
  receiver is just a non-starter to me.

And if I'm meant to launch the application every time I get on the bus...
  why not just send a text/geolocated tweet instead? The infrastructure's
  already there, and it's much kinder to my battery.

This is correct.


Also, if people decide to log their bus journey the day after they have a bad
one, that's good. Reversion to the mean, baby!


And if that bus route is always crappy, well, that's rather the point.
