Here is an interesting Poll.
Number of licensed vehicles (cars/motorcycles/boats/planes/sleds/four wheelers) add up their cylinders divided by the number of licensed drivers in the household.
eg. We have an eight cylinder truck and a two cylinder motorcycle and we have two licensed drivers, so 10 divided by 2 is 5 cylinders per family member.
