ELI5: why are most cars front-wheel drive, but motorcycles and bikes are rear-wheel drive?

You're really going to need to dumb this down for me. I know very little about engineering and physics. For whatever reason, I woke up with this question on my mind. Hope someone can explain it to me.

Most cars are FWD for two somewhat related reasons; packaging and cost. Generally speaking, FWD powertrains are less complex, require fewer parts, and take up less room than a RWD car; this makes the car lighter, cheaper to produce, and increases cabin space. 

Motorcycles and bikes are RWD mostly due to the interference with the steering and/or engineering difficulties that would result from running a chain to the front wheel. It's much easier to run the chain to the rear wheel that never turns.
