many thanks for your interest in enviiroCar and GSoC. We're currently preparing topics that we are planning to apply for in GSoC 2016. These topics will be available in February 2016.
Feel free to try out the enviroCar infrastructure beforehand and think about improvements/topics that may be done. If you have any questions about enviroCar feel free to post them to the enviroCar discussion mailing list ([hidden email]).
