Why are fly rods made this way?

I was wondering the other day why it is that fly rods seem to always be 3,4 or even 5 pieces whether they are 6 feet or 10 feet in length.   Why so many sections?  Why all multi-piece blanks?

Alot of fly fishers have small cars? I think travel is a big issue and with the new ferrule design it really doesn’t affect the rods action as much anymore to be a multi piece. I still think the two piece rods cast and feel better but I buy three and four piece mostly because they are more convenient to store.
