Our world faces numerous social challenges presented by the everlasting demand for mobility and the impact this has on space and environment. Transportation networks in most urban centers are often packed, and any small disruption can easily lead to long traffic jams. Moreover, our transportation system, with its polluting emissions, has a negative impact on our habitat and on global warming. Beyond that, 1.2 million people worldwide are killed in traffic accidents every year. These phenomena detract from the pleasure and freedom we experience from driving.
They also endanger our health and cost society a lot of money.
