I say in Australia, but unsure if this question doesn't apply elsewhere as well.
The question is based on a litre bike or larger at a price point of $20K-$25 vs a small car.
The car has a greater mass and a lot more consideration in it's design as production, has stuff like doors, boot & bonnet, seats, upholstery, air con. lighting, seat belts & airbags,radio/stereo/speakers,widows, 4 wheels + spare, locks etc etc etc as well as the ability to transport 5 people.
Forgive me if this rather trivial question has been raised before, but I don't recall seeing it
