Until the power density of the batteries approaches that of conventional fuels, electric aircraft won’t achieve the same usefulness. I can see it used in motor gliders, and around the patch puddle jumpers, but many years away from approaching the same usefulness of a C-172. I may have missed it, but a 100 miles out and 100 back for that $100 burger still hasn’t happened in a practical aircraft. These proposed electric hovering air taxis still can’t get past 30-60 miles and would spend nearly all of their time recharging as 1 or 2 trips and the battery is depleted. Electric cars are just now getting to the practical point, and their weight issue isn’t a problem for them, and none of then could do a 600 mile day trip in a reasonable amount of time.
