First, at single occupancy, EVs are comparable to traditional Internal Combustion Engine cars at full occupancy so carpooling is still very important if your goal is to minimize carbon footprint. Next, comparing single occupancy across eVTOL and EV it's easier to compare directly with specific models of eVTOL at 50 mile range, for example. EVs average around around 400 Wh / passenger mile.

A) KH Heaviside was actually on track to be twice as efficient as the average EV but that program is no longer active.

B) Joby 5-seater: 800 Wh / passenger mile

C) Archer Maker: 900 Wh / passenger mile

D) Beta Alia-250: 1200 Wh / passenger mile

E) Lilium Jet: 2400 Wh / passenger mile (note that for trips exceeding 150 miles, efficiency should reach around 1300 Wh / passenger mile overall).

The trade-off for supporting adoption of eVTOLs alongside EVs (which are approximately 2-6 times more efficient than eVTOLs for trips around 50 miles distance) is that eVTOLs can reach time-sensitive destinations more reliably than EVs because they are not constrained by heavy traffic delays, road closures, trains or natural disasters like floods or storms that block streets. The air ambulance use case is particularly compelling. The golden hour to reach a victim and get them back to a hospital is plainly harder to achieve if we rely exclusively on ground based ambulances.

And eVTOL as Air Medical Service programs as compared to conventional helicopter air ambulance aka MedEvac will be approximately 6x cheaper so hospitals should phased out their conventional helicopter fleet and purchase 6 eVTOL air ambulances for every new helicopter that they would have acquired otherwise. Think about how many more lives we could save with 6x as many air ambulances available at a hospital for immediate dispatch.
