And under those conditions, I have consistently seen a significant, measurable improvement in fuel consumption in real world driving (vs. that as-controlled-as-possible steady speed testing).

AKA range anxiety. Once you understand how much energy is available, and learn to monitor consumption (voltage, simply), it can be managed.

I also drive an EV. I understand this. It doesn't cause me to fret.

I'll be the first to say disabling the alternator is a complicated and not particularly user-friendly mod. I don't usually recommend it to people who aren't willing to put in the effort required to reap the gains. It's definitely not a "set it and forget it" situation.

EDIT: Also, you need to do the math. If your goal is financial savings, it could be a wash, since you'll be burning through and replacing batteries at a faster rate. (I have a source of cheap/free used batteries - not an issue to me.)
