Agreed.
There's a problem with mods, per se, and it's where they fit.
The first order of business (after vehicle spec; which is one sufficiently sized to carry all family members; thus eliminating other vehicles) is an analysis of miles on an annual basis.
DHS reported that 90% of us go 90% of the same places 90% of the time.
Reducing annual miles to achieve the same ends is the first "eco mod". Not only to combine trips, but sort the trip routing for best FE effect.
No last minute trips to the store. Etc. Accept the consequences of bad planning. Become better.
The point of private transportation is simply to avoid public conveyances or having to walk or bike. Time. Make those the alternatives.
Next is length of ownership. 12-15 years from a brand new vehicle. Fully enclosed garage. A family budget that prioritizes vehicle expense.
Reduce the miles.
Reduce the lifetime number of vehicles owned.
Sacrifice other desires so that the vehicle is fully funded. Money just sitting there.
Etc
Then (only then) do other changes make sense.
Feedback instruments
Pre start engine warming
Etc
Most "mods" don't pan out when applied under this. There's not going to be a significant percentage change to the annual average mpg.
