Or, just do nothing

Snopes covers the myth that it is the rubber tires that makes cars safer in a lightning storm (turns out it's because the metal frame acts as an ad hoc Faraday cage -- who knew!).

They conclude with a list of tips to protect yourself from lightning strikes, which includes such gems as avoiding doorways (yes, doorways) whenever you hear thunder.

The article also mentions that 58 people per year are killed by lightning. I'm pretty sure at least 58 people per year are killed in auto accidents while they are on the way to the pet store to buy dog food, so therefore nobody should own a dog.

Seriously, for causes of death which are that rare, it does not make sense to change your behavior one iota to avoid them.
