Maintenance on bicycles is also insane. An "oil change" (clean and lube the chain) every 300 km or so. Even if you consider that bicycles don't travel as fast and far as cars, that's quite an annoyance to deal with about every 20 or so operating hours.
If you were to actually pay a shop to do the maintenance, I suspect a bicycle would be more expensive per km than a car.
