Seriously, based on my understanding of WHY the tachometer exists, why are there tachs on vehicles with automatic transmissions? Most automatic transmissions have low-gear settings. It would be a good thing to know when you're at the upper range of one of these.

I offer the following; it hasn't to do with why or when to use a tach with an automatic transmission, but rather why there's a tach in an automobile with an automatic transmission at all.
It's more cost effective for the manufacturer to include a tach in all models where a tach would otherwise be an option. As I postulate, it's cost effective from the design, manufacturing, procurement, assembly, and all other aspects for the manufacturer, not necessarily the consumer. All consumers pay a small price for a gauge few will ever use, even those with a manual transmission.
This is especially apparent when you consider the similarities (i.e., cost effectiveness) among models, not only with the gauges, but also the supporting electronics as well.
Similar to, but different than...why are automatic transmissions even offered in certain vehicles, for example: Jeep Wrangler, Corvette, and
4x4 Trucks. I already know the answer, but it still makes me laugh a bit when I pull up next to a "sports car" and look down and see an automatic shifter.
