gears are expensive, they have backlash, and they're noisy.

Gear drives are noisy and are expensive for overhead cams so they're not used in modern mass-produced cars. They were mostly found in pushrod engines back in the day where the cam was close enough to the crank that only 2 gears were needed, like early Subaru boxer engines.
