Urban air mobility (UAM) is a point of convergence for automotive and aviation organizations. This presents opportunities for collaboration between the industries, with air taxis being of particular interest. Intended to transport a few customers at a time, avoid congested streets over short distances, and reduce pollution, this category of aircraft is often envisioned as an electric vertical take-off and landing (eVTOL) vehicle. Startups and established OEMs alike have begun moving past ideation and into the development stage for these next-generation aircrafts.
