This is so silly/immature. In 10-20 years all the cars at the pump will be waiting in line at the EV charging station. Just another “hey look at my tesla” asshole

Very interesting video along with the comments and additional videos that follow.
Loved the one about the Tesla Solar Roof and Powerwall during the storm.
I dumped most of my Tesla stock yesterday but once we get by this Bidinflation I'll be buying back and than some.
That dude needs to read this article about Florida gas stations and generators from back in 2017:
How do gas stations pump without electricity?
AsHurricane Irmawhipped through Florida, many residents made both plansandback-up plans to brace for emergency.

Depending on how long the power is out, those gas stations w/generators will be refueled (if needed) and up and running via generators while the power is still out, giving an advantage to ICEVs.
If the power is back fairly quickly, then it doesn't really matter either way and there's no advantage for EVs or ICEVs.
The gas stations that do have generators have lines 2 miles long and run out of gas in hours.That dude needs to read this article about Florida gas stations and generators from back in 2017:

Doesn’t anyone remember Sandy? It was like mad max for at least a week.
That's not right, either. People with EVs will have charged the vehicles overnight before the storm landed. EV owners could drive out on a full charge. No need to be jealous.
The Science of Why Electric Vehicle Batteries Are So Dangerous
In a recent op-ed, the Washington Post outlines how Tesla’s battery issues and fires may not just be due to poor design and manufacturing but a side effect of electric vehicles relying on lithium-ion batteries.
The Washington Post reports in an op-ed titled “Tesla’s Big Batteries Aren’t the Fire Problem. Lithium Is,” that Americans should be questionubg whether lithium-ion powerpacks should be used for applications such as electric vehicles. The piece argues that the science of lithium-ion batteries make them inherently dangerous.
The large-scale use comes with significant risks, although most modern power systems choose this formulation because it boasts higher energy density, as well as greater charging and discharging efficiency. However, lithium-ion batteries have a volatile, flammable electrolyte. So, while there are safeguards to avoid fires, all the combustible ingredients are still there. Flames can accelerate through chain reactions, known as thermal runaway.
Big batteries are made up of several cells packed together. Current is constantly flowing inside, which generates heat. If there are no barriers between the components, a failure in one part quickly cascades through. While elaborate (and critical) equipment for cooling the system is put in place, it draws on the energy of the actual powerpack and reduces its output. In addition, when charged, a coat of lithium metal can form on the surface and dendrites, or needle-like structures can grow, and lead to short-circuits.

Somehow I don’t think the geniuses who forgot to fill up in the days leading up to the storm won’t remember the plug their car in the night before the storm either.
Uh, the beauty is one can be done at home while you sleep because most of us plug it in as part of a daily routine. There’s no “remembering.”
As for getting gas right when everyone else wants it in long lines before it runs out…many folks on the news had to “hunker down” because they waited too long.
I can't argue with that, LeBusDoor is right. I charge the EV at night when I take out the garbage. It is kind of automatic.
Breitbart? You can't expect anyone to take this seriously. Maybe in Russia, but not here in USA.
This just in:
Batteries might be a fire hazard.
Gas also might be flammable early research shows.

The original story is from the Washington post, that’s legit right?
There was no substance. Point, meet BrotherSkinny. BrotherSkinny, meet point.
Just saw this on Facebook but cannot cut and paste. If considering buying an EV you might want to read this.
I guess the mods are no longer allowing me to post links in threads. I posted the link but it doesn’t show up in the post.
Yet considering how many tens of millions of cars on the road car fires of ICE engines are rare. These electric cars that use lithium ion battery packs seem to burn relatively often. I’m sure there are statistics on it I will try to find them.
Yeah, but to be fair, lithium batteries are problematic. There have been several cargo hold fires on aircraft from Li battery cargo. The initial Li adoption on cruising sailboats has all but completely shut down due to several hull losses caused by battery failure.
It's an efficient but kinda shitty technology. It will have to be deselected, and I suspect fairly soon.
But this is really the problem with battery-powered cars, at the moment. The storage platform that underlies the entire system is, in all cases, inefficient in terms of both power density and recharge time. That will change, over time. But that time has not yet come.
Generally speaking, I like the idea. But I don't particularly relish being an early adopter and the ranges on all the cars I really like just aren't suitable to my use case. A PHEV, maybe. I could see that. But justifying the cost for some reasonable amount of performance is a challenge.
Thank you for having a rational discussion. Some on this board just want to shit you down for having an alternative point of view!
My position on electric vehicles has been pretty consistent. As has my position on autonomous operation, which will never fully soak as long as the systems are based on purely onboard data. Extra-vehicular communication of data, to and from the infrastructure as well as other vehicles, is the golden ticket.
When I wrote that white paper on V2V/V2I, I cited a short term use case that got a great deal of attention among northern DOTs because it addressed a major budget line item.
In the snow belt a DOT's single greatest expense is treatment chemicals. You see them being applied all the time - in even layers over an entire roadway system. It's prohibitively expensive, especially when they have to go to a second application to address reports of icing.
It's inefficient because they don't have a means to identify specific trouble spots (other than historical knowledge). There are periodic roadside weather sensors that tell them temperature and humidity but not specifically how slick the road surface is.
Ya know what does have all this data? Every single car. Temperature and humidity are directly sensed and communicated to the ECU and Body Control Modules. Surface friction is aggregated by monitoring ABS and VSC activations. There is also precise location data available, as well as velocity.
All of these parameters can be aggregated to create a "cold map" of road conditions. Treatment can be dispatched to specific areas where needed. The estimated savings is on the order of 40% to 60%, depending on climate.
Achieving this goal would require that the vehicles and the roadway infrastructure communicate with each other. The vehicles would provide the raw data, the infrastructure would in turn provide condition data to the vehicles - in the case of an autonomous vehicle, automatically communicating the need to slow down and perhaps even tighten up stability systems in areas where there are traction loss.
This is the kind of stuff we need.
Maybe they will drive out. Maybe they won't. Some won't have access to home chargers. So they'd be stuck in lines a mile long to charge and won't get it done in time. Especially years from now when EVs are so much more numerous.
Meanwhile, folks with ICEVs can also fill up the night before and drive out. So nobody would have any reason to be jealous. Except all the EV owners without home charging capability.
And again, if cars can drive out, fuel tankers can be driven in to refuel the gas stations with the generators. And if electricity is down for a weeks, and it's hundreds of miles of power outage, that's still a problem for EV owners who can charge at home.
I'm not trying to say that's a reason to not promote EV adoption. I am saying it's a reason for state and local governments in places like FL to plan ahead and make contingencies to accommodate huge numbers of EV owners without home charging facilities, just like they've done with the requirement for critical gas station to have generators to power pumps in a crisis.
That is a good example of a contingency plan for post-storm power outage charging. Places like FL should ensure there are plenty of such facilities for emergency situations like Ian.
That kinda of data transfer is way off into the future. Most cities cannot even get their trains to run on time.
Mild if power is out all across the state or a good size area, what you gonna do?
Let’s be honest: no one wants their car to be able to communicate information that could potentially be used against them in court.
Imagine getting into a car accident and the other party is suing you because your front left tire was off spec by 5psi or you needed a wheel alignment…

Most trains are not managed by cities. Nor is highway infrastructure.
And trains do run largely on time.
I'll save you the trouble. More egg for you.

I mean are you assuming that in 10 years there would be more EVs but that the grid would be exactly the same? I doubt that.
I've ridden both extensively.
They are on time the majority of the time. NJ Transit rail performance OTP for August 2022 was 91.5%.
NYC subways (all lines) are averaging 83% on time for the year.
It's a problem today. But for the future, solar and wind energy can be generated and stored and used to charge EVs in emergencies. The same natural gas generators used to power gas stations can also be used to charge EVs.
It is correct to say that ICEVs are a better bet in a situation like Ian today, despite EV evangelists defensively trying to state otherwise. But ICEVs are going away, sooner or later. So solutions will have to be found and implemented, and probably pretty soon.
