You’re locking in on the wrong thing.

In 60000 miles, the above poster reports one gallon of gas was saved. That’s 0.05% assuming 30mpg. We don’t need hundreds or thousands of changes that each net us tiny results, we need big changes that can happen quickly and net tens of percentage points of improvement. Yes, small changes are not literally nothing, but solutions need to look like “40% fewer cars on the road” sorts of things if we want to actually accomplish anything at all.

The world doesn’t have time or space for us to make these minor, rounding-error changes. I know the argument will be “every little bit helps” but we collectively need to start making massive changes, and stop thinking of this as an incremental problem. We should still make improvements and strive for better efficiencies, but the practical reality is that those changes are too small, too slow, and too late.

While I certainly agree with your overall point, I’d guess that firefighters have someone who’s job it is to start the engine/truck while their fellows are donning their gear.

Let’s not, the idiots running the show in the US will just rename it to the Gulf of Patriotism or some dumb bullshit.
