Now I need to google the word "Pillion"

[Melinda Mills]

"Pillion" = a seat for a passenger behind a motorcyclist.

It is not customary to say  "driver" for the one on the pillion.   One says "motorclyclist" for the one in front steering and "rider" for the one behind. So it is pillion rider, not driver.  "Driver" is technically correct for the one in front , but not often used.  Of course the proper use of the English Language is no longer in vogue.
