Much more important to figure out how to get a 15 MPG vehicle to get 20 MPG than to figure out how to get a 50 MPG vehicle to get 55. I basically don't care if the Prius ever gets better fuel economy because the difference between $0.06 per mile and $0.055 per mile isn't that important to me.

Same here. Driving an efficient car also makes most ecomods one could do money losers.
The Pilot Sport tires I put on the Bolt dropped the summer efficiency from 4.7 miles / kWh to 4.1 miles / kWh. That is a 13% drop in efficiency which in my experience is about average when going from crappy LRR tires to a good performance all-season.
So do I care? NO. It is the difference between $0.015 / mile and $0.017 / mile. 2 tenths of a cent per mile or $2 a month. That is a very small price to pay for a safer car.
