The image shows a preview of a future production version of the PUMA. Much better looking than the prototype. These things have to look like something from Apple, they can't look like glorified wheelchairs like the concept.
But a lot of rethinking has to go into cities in order to adopt a fleet of PUMAs. Maybe they could be viable in areas closed to cars. In such situation the PUMA or similar personal mobility vehicles could complement the public transport system.
