Well, of course you are going to stall the engine sooner or later. That is not the issue at hand.
I assume we are all "smarter than a fith grader".

Agreed :D

But you would be surprised at how many are not as smart as a fifth grader lol. (not talking about anyone of us on YW heh)

Was their any particular reason anyone knows of as to why Toyota cheaped out on giving us a tach on the manual, yet the Sedan S comes with one? I mean even a base model Mazda 2 comes with a small, yet functional tach.

Many auto manufactures often do strange and nonsensical things like that.
It can most likely be originally be traced to cost cutting measures.
Coporate accountants live in an esosteric, alternate reality.

I pretty much cruise between 1600-2000 rpm all the time, where it has plenty of (gentle) acceleration on modest hills and never complains. (1.5 liter 5 speed manual)

My old FX usually has to stay above 2000 because there's no torque left at lower RPM.

You are failing to factor in the added resistance of the trans input shaft (to turn) on the crank when you are lugging the engine. All this added resistance is transfered to the WPs and crank.
It's basic physics my friend.

There is no such added resistance of the trans input shaft. You're right, it is basic physics.

Perhaps in an alternate universe.
If there was no added resistance, there would be no need for different gears. The sole prupose of the various gears is to overcome the added resistance at the input shaft when needed.

I'm too old to argue that 1+1=2

The Canadian manual versions have a tach.
