Honestly, it's more that I don't care enough to actually look at/into the numbers.
It seems to boil down to the fact that people don't use them as intended and/or governments have policies that force people into mis-using them (i.e. the EV mode in cities, vs. optimal usage).
Maybe them scientists at T&E didn't "forget" to factor human nature, but the results of the study sure do show that the natural human inclination toward laziness or status quo is a big factor as to why Plug-In Hybrids Are Five Times Filthier Than You Think They Are and why the automotive industry is calling to weaken the regulation for car CO₂ emission standards:
Big shots at EU regulatory agencies ain't puttin' in the effort to understand real world behavior of PHEV drivers when calculating emissions numbers
PHEV drivers ain't plugging in as often as the big shots at EU regulatory agencies expected, either due to laziness or because they can't
Big shots at automakers and suppliers ain't puttin' in the effort to further develop Europe’s growing EV value chain
When Rivian first rolled out, with their Ford investment, I had hoped they’d use Ford as a “ghost kitchen” for service. Why build out that infrastructure? I’ve been wondering if Scout/Rivian won’t do that on some level. It would seem like there could be mutual benefit to both (For instance imagine if Lucid partnered with Mercedes for example).
Relying on independents seems fraught with issues. I cannot imagine taking that gamble on investing if I owned a shop.
Call me a skeptic but I seriously doubt they “forgot” to factor human nature. It’s more like it fit their agenda better, hence went with biased assumptions.
It’s not that complicated if we focus on basics. In 2023 average USA electricity generated a reported 0.81 pounds CO2 per kWh. It’s improving gradually every year but let’s use that for now.
When we adjust for typical electricity transmission inefficiency and also vehicle charger inefficiency, we end up with approximately 450 grams of CO2 per kWh of electricity that ends up stored in vehicle battery.
Since many BEV or PHEV (in EV mode) SUVs perform in the range of 3 miles per kWh, it follows they generate around 150 grams per mile. Large pickups as example can be much worse than that. Europe may have cleaner electricity generation and they generally also drive smaller vehicles, but 35 grams per km (56 grams/mile) seems way too optimistic in the first place.
Many local mechanics throughout the Midwest are takin' seriously the growing demand for independent EV maintenance/repair shops and makin' that investment. Tire shops too. Tire Discounters opened TD/EV in Mason, OH
It is simple-they assumed that people would always plug in their vehicles and use EV mode, but what is actually happening is people aren't charging the vehicles either due to laziness or because they can't. They went with the best case instead of worst case when making estimates, because they forgot to factor in human nature.
The big shots at Ford went on a major decontenting blitz for 2026 Mustang coupe/vert. EcoBoost Premium (200A) got hit the hardest:
Auto-dimming Rearview mirror changed to Manual Flip Framed Rearview Mirror
Aluminum Foot Pedals replaced with Black Rubber Foot Pedals
Replaced Heated, Pony Puddle Lamp Sideview Mirrors with Sideview Mirrors
Magnesium Framed Panoramic Curved Display deleted, replaced by Separated 12.4” LCD Digital Cluster w/ IOD Message Center and 13.2” LCD Capacitive Touchscreen
Universal Garage Door Opener deleted
Illuminated Door-sill Scuff Plates deleted
Floor Mats – 1st Row Carpeted, are no longer standard and are now optional
18” X 8” Two Tone Machined-face Aluminum with High gloss Ebony Black Painted Pockets changed to 18” X 8” Painted Silver Cast Aluminum (pics below)
