There's nothin rubber tires or shoes are gonna do for you in a lightening strike. You think if a spark is gonna jump several thousand feet from a cloud to the ground where you are standing that a couple inches of rubber is gonna make a difference?! No way!! The only reason you are safe in a car is that the electricity will travel around the outside of a metal object. So just keep your hands inside the windows and try not to touch the body if you have exposed metal inside, like an old truck or something with no headliner. If you on a bike. Find a bridge or something....
