The best way to survive, of course, is to avoid a lightning strike.

Oh, and remember that rubber tires and rubber-soled shoes provide virtually no protection from lightning. In fact, many victims of lightning strikes are farmers in open fields riding tractors with rubber tires.

Rubber tires and soles don't protect from a strike, no, but they do offer at least some protection from the step potential[0] a nearby strike would cause. Of course with everything being wet from the rain and all the protection is most likely rather limited.

And often metal farming implements dragging the ground, and a vehicle that sometimes makes your head the highest thing from the ground. Maybe not the best high level evidence that tires on a car don't help.

The high level evidence is that lighting can travel thousands of feet through air. An inch or two of rubber is nothing.

It's the metal cage of the car that provides lighting a more conductive path around instead of through you.

Better evidence is that the lightning has already traveled through hundreds of feet of air which is a much better insulator than one foot of rubber.
