Who is driving
Two retired bus drivers, one more route.
This started with two real bus drivers, now retired. She drove city buses and coaches, then delivered new buses from factories to dealers across the USA and Canada, plus straight trucks from dealers to their buyers. He drove coaches and school buses, and also delivered new buses and motorcoaches across the USA and Canada.
Between them, over 2 million miles with no at-fault accidents.
Behind the wheel is the Driver, the mustached guy you see in the art. He's a character the two of them dreamed up.
The Bus is how they share the road with everyone, pointing out places you might have rolled past without noticing.
