Do the math: you'll get enough electricity out of a modern battery to
run a ducted fan long enough vertically lift the battery, the fan and
some sort of lightweight chassis, for a few minutes. Not enough spare
energy to lift a person, let alone travel 300 miles carrying one.
Someday, sure. But not today.

It is hardly too strong to say that the Constitution was made to guard
the people against the dangers of good intentions. There are men in all
ages who mean to govern well, but *They mean to govern*. They promise to
be good masters, *but they mean to be masters*. Daniel Webster

What is the range of a Tesla?
That range is not so much flying time at that speed.

Little over an hour battery life.

Its maiden flight was a demo of an incomplete and impractical system.
A power source which can deliver 10-100 MJ/Kg is required for that to be
practical. Batteries deliver on the order of 0.1-1 MJ/Kg. Fuel cells
can deliver enough MJ/Kg, but not the required rate of power.
And hopefully self-driving will be practical once that advance in energy
storage is made. Learning to fly an airplane has taught me not to trust
most people I know untrained in flying machines.
Still, when they are practical, I'll ride one. I bet it'd be fun.
