I was at a talk given by the president of Embraer-X (that's an Embraer subsidiary that looks into these riskier ventures), and he got into the details of how they validated their business plan of using these vehicles for urban transportation.

They offered helicopter rides to one of Rio's major airports and charged R$100 per passenger (according to him, that's an accurate estimate of future prices once they make their eVTOL) at a loss just to see if there was demand. They got booked the entire year in advance.

That is mostly because Brazilian traffic and public transport is atrocious given the city size.

Rio de Janiero is a bit larger than Moscow, Paris and Guangzhou yet each have at least 5x the metro infrastructure.
