Innovations in the area of mobility often take years, sometimes decades, to become reality. Developing technologies over such long time spans is a risk, since it is unclear whether the public will accept the new technology, once available. This raises the question whether it is possible to evaluate the acceptance of a technology, which cannot yet be tested under real live conditions. Industry and researchers have come up with different solutions to this challenge, using descriptions, sometimes pictures and increasingly also videos and virtual reality demonstrations of the new technology.
