Looks like Embraer is seriously involved in this project. Check out their Flight Plan 2030 white paper.

A new generation of aircraft, called electric vertical take-off and landing vehicles (eVTOLs, pronounced ee-vee-tols) will soon enable us to redefine the urban mobility experience. Although some eVTOLs may look similar to a helicopter, they will be powered by batteries, hybrid engines, or other new technologies that will make them much quieter than the helicopters of today. Advanced avionics will enable eVTOLs to navigate with high precision, exchange information digitally, and respond to changes in flight conditions autonomously. At initial launch, many eVTOLs will have pilots on board. With time, however, these aircraft will mature to a stage where they will operate autonomously.
The introduction of eVTOLs will challenge our assumptions about urban air mobility. Urban flights will become more affordable, in part, because eVTOLs will use less or no aviation fuel. With no runways required, passengers and goods will depart from “skyports” or “vertiports” (i.e., areas with take-off and landing [TOL] pads) positioned at different locations across the city. From there, they will traverse over an urban area to another skyport in mere minutes. To date, more than 70 companies have already invested over US$1B in the development of eVTOL concept vehicles (Booz Allen Hamilton, 2018). By 2035, forecasters estimate that 23,000 eVTOLs will be serving a global market worth US$74B (Porsche Consulting, 2019).
