Because it's nice to know what RPM you are operating at, good for diagnostics, and You can manually select which gear you are in, and you need a tach to know when to shift gears.

Mostly user entertainment unless the user is racing.

Folks were shifting gears manually long before tachs (not "tacks") were standard equipment.
