Wall Street Journal: For Maximum EV Efficiency, Stick to 25 Miles an Hour, Ignore Angry Drivers
Saw this article posted, figured it's rare to have hypermilers in the news at all. Enjoy!

Sorry for thread-jacking the most recent EV post, but....

I'm still holding my breath from 3 years ago when this fabulous news was rumored;
https://ecomodder.com/forum/showthre...ite-36954.html I'll have to ask Alberto for the latest, and continue holding my breath. |
Might explain the sudden prolifferation of high visibility student driver signs here in Reno. Cant be that many driver schools, can there?
|
I wonder what the purpose of student driver signs is? Not like I drive any differently, because they still have to obey all traffic laws. My assumption is there are a lot more driving teachers these days. I'd bet the majority of kids get paid instruction. Back when I was learning, that was hardly a thing. Nobody I knew had paid instruction. At 15, I did all the driving when accompanying my parents, which is how I learned.

My thoughts were: keep you from being violently assaulted post faux paus driving incident. Cut some one off and not get shot, perhaps

Driving slow
When I drive my wife's car, C-Max PHEV, I always turn on emergency flashers if I know I am going to drive 10MPH or slower than posted, so far *knocks on wood*, nobody has honked their horn or gave me the #2 salute :turtle:
|
Ah, laws must have changed.
I think when I was 15, I just had to take a written test and pay a minimal fee to get the learners permit, which allowed me to drive whenever I was accompanied by an adult licensed driver. At 16 I just had to pass a written and driving test, pay another fee, and got a full license. Motorcycle endorsements required a class to be taken if someone was under something like age 25. For a highschooler, the $250 fee for the 2.5 day class was pretty steep, but well worth it. |
For maximum EV efficiency, drive a car that has minimal drag, frontal area, and mass.
My electric velomobile uses about 7 Wh/mile to do 30 mph with some light pedaling. There is not a car on the market that could do that. There is not a car on the market that even does 10x that at that speed. The automobile industry considers efficiency as an afterthought and has been doing so for its history. The industry's benchmark sports cars are designed in a manner that runs counter to their stated purpose in the name of preserving planned obsolescence, corporate aesthetics, and tradition based upon the horse and buggy of yore, which ends up hurting the maximum possible theoretical performance the vehicle is capable of. There is zero reason some major automaker could not build an electric two-seater that only needed about 60 Wh/mile to cruise 70 mph on the highway and reach 200 mph with stability while only needing 100 horsepower to do so(and then shove 1000+ electric horsepower in it in the interest of performance), or a 5-seater sedan that could do 70 mph on 100 Wh/mile. Universities have built solar-powered prototypes with efficiencies in this ballpark or better. And when you start considering single-person vehicles, 15-20 Wh/mile @ 70 mph on the highway is also theoretically possible. |
