Long commute time. During hot summer days using public modes of transportation can be tiresome.
Electric vehicle (no sweat, yay!) smaller than a bicycle, so that you can take it into a bus (or a tram) when it starts to rain.
Probably not earth-shattering, but definitely improves one's quality of life. Also it arouses interest in other people ;)
Riding the board requires some skill, but it's not that difficult to grasp. Just put your feet on the board, move the throttle trigger on the controller and that's it!

The project is mostly finished and I've regularly used the board for the last few months. So far I've covered around 200km on this board and I can say that it can be used as an everyday way to commute (assuming the weather is ok). Currently I want to assemble and write firmware for Front Lights module (which I will document here, on hackaday.io). Apart from that, I still have a few ideas for minor improvements.
