The conversation highlights the advantages of hovercraft and wing-in-ground-effect crafts as all-terrain solutions, noting their ability to float if they lose power. Concerns are raised about the practicality of flying vehicles in urban environments, including noise pollution and safety issues. The PBY Catalina is mentioned as a historical example of a versatile vehicle, while the idea of a flying submarine is playfully suggested as a future challenge. There is skepticism regarding the viability of current flying car prototypes, with discussions about regulatory hurdles and potential public resistance due to noise and safety concerns. Overall, the thread reflects a blend of enthusiasm for innovative vehicle concepts and caution regarding their practical implementation.
