Volts per meter in air is nothing if you are a 6 foot tall 50 ohm resistor.
Resistance makes it futile.
(until the lightning bolt actually hits).

15 kV/m is an electric field of 15,000 volts per meter. If you are
outside in a strong thunderstorm, the electric field due to charges in the
cloud can get as high as 15 kV/m or even higher. If the field is this
high, lightning may be imminent. If you have a Tesla coil generating
500,000 volts, the field in its immediate vicinity could be 250,000 V/m.
Walking across a carpet on a winter day can generate fields in the
vicinity of 1 kV/m or 1,000 V/m.
