Your most number one essential task as a parent; defend your kid, defend your family.

Also, with transport, the most important thing is to see your car or vehicle as some sort of tank, something which could withstand foreign attackers.

Think about the tail event; if your car got in a really really bad accident, would you, your wife and your kid be unharmed?

Perhaps best to think of your car as a third skin; armor.

Also, maybe it is best to think of your house like some sort of defense center.

Whoever has the best defense shall win the war.
