Also your comparison is for a non certified aircraft, these Air Taxis will need to be certified with the attendant costs that come with certification.
battery technology is the main thing that has limited the advancement of any EP machine and will continue to be so for a very long time yet! Weight, storage capacity, cost and replenishment time will always be what holds back this fanciful idea on a large commercial scale.
