Another interesting metric would be to adjust brightness based on length of journey.

Unfortunately, only in the touristic areas, and near the "Ecobici" routes, there are bike-exclusive lanes. On the other side, drivers feel entitled to use the streets exclusively, and they perceive bikers as a hindrance in their way.
I wanted to commute by bike to my work, but at the end I gave up, because I didn't want to get hit by a car and risk my life like hardcore bikers do.
Otherwise very cool!
While I'm giving feedback, I must say I had to pause and re-read this sentence many times: "Human helps people move almost twice as much in six weeks". As I'm not familiar with the app, I went straight to that sentence and was baffled about some person who helps people change their place of residence a lot more for 6 weeks, but a lot more... compared to what? Took a while to arrive at "An app named 'Human' helps get people to move around more than they otherwise would within six weeks of beginning usage".

Moves (http://moves-app.com) is also good for passive location tracking. Good data export options and some nice mapping integrations with third party services (http://quantifiedself.com/2014/03/map-moves-data/). Disclaimer: Moves is a Facebook entity so caveat emptor

I basically want my always on and exportable Moves (http://moves-app.com/) data to port into "Personal Heatmaps" of Strava.
Ditto Vancouver where I originally come from - lots of activity downtown and in rich, young neighborhoods, but nearly zero activity in middle class or older neighborhoods.
It's not just selecting for iPhone users, it's selecting for wealthy, young, iPhone users. On a more meta level these maps are an interesting proxy for wealth, race, and age.
