I am back to inform that the suite is in the process of introducing Game Center features to enhance the collaboration of its users to the benefit of the environment. This activity should also comprise the establishment of a voice chat communication between users and with taxi drivers, if possible and not attainable by some new methods in the oncoming iOS 8.
In brief those are the leaderboard introduced:

• Most faithful users

• Taxi bookers
• Best Sharers
• Bus pickers

And the collective leaderboard for the three latest ones aiming at establishing the most committed users to the environment:

• Best environment savers

Moreover a number of Achievements have been introduced to mark specific feats and this are the following:

Big social walk
A walk with four people.
Full car sharing
A car ride with four people.
Taxi sharing
A shared car ride with two other people.
Globetrotter
A user having used the app in 20 different locations.

Specifically now I am waiting for the specific graphic pieces to arrive and to localize the new features and some additional test in order to release the new version.
