Things are not going well for today's commuter. The big cities are becoming more and more congested, and both home and office are becoming increasingly difficult to reach. Colleagues come out of the traffic jam stressed and frustrated. And often they are late. Because they still have to find a parking space, of course. And the spots they can find are expensive. Things are not much better on public transport during the rush hour. Crammed compartments and the risk of delays is always lurking.
