Just get rid of the charging stations. It’s ridiculous that EV owners should expect to charge their cars anywhere but at home or at work.

They must have a lot of copper. Thieves are going target them. What can you do in a land of criminals?
Considering the voltages and amps going through it is safe to assume those are fairly thick solid copper wires yes.
Call the coppers on them!
Oh…
Fix the system so people don’t have to make money by stealing copper.
And yet, here we are with billionaires in charge—robber barons v2.0.
I just think installing these BEV charging stations everywhere is a bad idea in the first place.
I’m going to disagree with you on the sentement. We need a better infrastructure for EVs, and non-tesla vehicles can use those charging stations (either via adaptor, or a few use that same plug type.)
Wait, do they not all use the same plug? Forgive my ignorance on EVs, my car is 60 years old.
With ya on infascructure. Would like to see better build quality than tesla stuff though, and hardware you own not locked behind pay walls. Add standardization to the list I guess.

This guy has done several videos on EVs and their plugs but this one is what I feel is most relevant.
Hah cool I like that guy. He definitely makes some interesting points. I’m glad theyre moving to an industry standard though.
Why would it be ridiculous for EV owners to charge cars away from home or work? l’d say that it’s pretty necessary for long-distance trips.
EDIT:
Long distance power transmission is normally done with aluminum lines, rather than copper.
anixter.com/…/copper-vs-aluminum-conductors.html
Resistance is a function of the material’s conductivity and the cross-sectional area of a cable. If aluminum has 61% the conductivity of copper, then one needs 1÷0.61=1.63 times the cross-sectional area for an aluminum cable to have the same resistance. That’s a radius 1.63^0.5 = 1.28 times the radius of an equivalent copper cable.
So you only need an aluminum cable with a radius 28% larger to achieve the same overall resistance.
In the case of the EV charging cables, flexibility is at a premium, and increasing the radius decreases that. But my guess is that it’s probably within the range of acceptability to use a bulkier aluminum cable, if need be.
EDIT2: I was also going to suggest liquid-cooled cables, which electric arc furnaces use for their power busses. Apparently Tesla already tried using experimental liquid-cooled cables, a decade back:
electrek.co/…/tesla-ends-its-thin-liquid-cooled-s…
That would have been liquid-cooled copper, but one could presumably also do liquid-cooled aluminum. That’s another option, if one wants to keep heat under control with higher resistance from a cable. Probably some extra cost for the cooling system, and there’s some extra waste of energy as conversion to heat that way, but I doubt that it’d make EV charging impractical, were that what was required to deal with people stealing copper.
Battery powered EVs should not be used for long-distance trips.
I mean…I agree with you that EVs are relatively-poorly-suited compared to ICEs for long distance trips, and if I had both a gasoline-powered and electricity-powered vehicle, I’d use the gasoline-powered one for a long-distance trip… but not everyone is going to own both. It’s hardly reasonable to say “well, people who own EVs just can’t travel long distances”.
Take a bus or a train. Public transit is of course the real solution. Transitioning from ICE personal vehicles to personal BEVs doesn’t really solve much and arguably creates more problems.
why the hell is that ridiculous? People do go places other than home and work. People take road trips and vacations. Electric cars are a good thing, just because one particular brand is owned by a narcisist ruining the country.
I don’t care about any particular EV brand. Trying to use battery powered EVs for such purposes means that they need to built with heavy, oversized, extra hazardous batteries. The responsible, proper use case for BEVs is short trips with plenty of time for charging at home or work.
So your suggestion is basically families should own an EV just for getting around home… and a gas guzzler for long distance travel? IMO the ideal should be a slow phase out of the gas cars.
Or you know… instead of needing super heavy batteries… they could have smaller batteries… if charging stations become common enough that people can relatively easily find places to stop and charge on long trips.
Batteries and liquid fuel are both hazardous in terms of catching fire, do you mean something else?
One can use natural gas (usually combined with some amount of gasoline). In terms of safety - if you’ve ever seen gas stations with concrete walls between fueling spots, that’s where this is popular, so not very safe.
I’ve not seen those (may not be in my country). What do the concrete walls stop, explosions?
It’s cheaper and more dangerous, and usually done where natural gas is much cheaper than gasoline. Yes, explosions.
And women should stay home and cook. Amirite?
Also, not everyone has a parking spot with electricity. How are you supposed to charge if you’re parking on a random place on the street, like most people do? I’d joke about “lower a chain of extension cords from your 20th floor”, but that would be assuming you can park next to your home at all. My building’s parking, for example, had all its spots sold out by now, while the very few ones for sale in the neighborhood cost a fortune. Apparently, they were affordable if you bought the apartment new, but on a secondary market - no.
EVs are for saving the car/oil cartels, not for saving the planet.
That is an interesting position. How do you figure?
Just get rid of the fuel stations. It’s ridiculous that vehicles owners should expect to refuel their cars anywhere but at home or at work
I’m inclined to agree that all motorized personal vehicles and their attendant infrastructure should be eliminated. However, you’re making a false equivalency. I live in New Jersey, so it takes maybe five minutes for me to completely refuel my car with gasoline. My understanding is that it takes six times as long to charge a big EV to ~80%. Therefore, a single fueling station can serve many more people with a much smaller footprint. Furthermore, fuel gets consumed, whereas batteries are mostly dead weight that occasionally do the thermal runaway thing.
I really like the “thermal runaway thing” expression, and yeah it is a false equivalency but it’s a funny one.
EV charging and the tech around it can be slow today, but it doesn’t mean we should abandon and go back to what we know is working (as some people want to). This is a recipe for zero innovation and not the way to become a Star Trek like civilization.
In my city there are electric buses that charge in a few seconds at some stops along the route. No overhead wires, no big diesel engines and no noise.
We just need to work and improve those new vehicles, find better than the actual EV and combustion engines as well.
Which buses are those?
My position is that the development of long range BEVs (and all the externalities associated with manufacturing and disposing of these batteries) has been an incredible detour. We already had the technology for fuel cell EVs with as much range as ICE vehicles. Meanwhile, short range BEVs are great because they solve the problem of refueling and avoid the problem of recharging, since you can do it while you sleep work. Long range BEVs just trade refueling for “fast” recharging, which is actually slower and more inconvenient than refueling. Where we really need innovation and development is in mass, public transit.
It’s the TOSA en.m.wikipedia.org/wiki/TOSA_(bus)
Nuff said.

Just get rid of the cars. Build cities built for human communities, not for cars and mega corporations. Electric vehicles are a band-aid solution that’s not going to save us, and doesn’t solve the fundamental problem.
The idea that EV owners should only be able to charge at home is a joke I hope? Should they not be allowed to travel?
No joking. Why do you think EV owners need charging stations everywhere in order to travel? They’re not restricted to using only their EVs, right?
Ah I see, EV owners should also own a gaz guzzling car only for going on vacation I see. Very good point you are very smart.
If you take a lot of long distance trips that it probably makes most sense to just keep a single ICE car. If you only take long trips occasionally then just rent one. Hopefully, buses and trains are also on option for you.
If you’ve got one of those BEVs capable of hundreds of miles of range, but you’re only driving tens of miles everyday, you’re not any better than an F150 owner with a clean bed.
.
What if you work remote and live in an apartment building without plugs???
Instead of socializing the cost of putting charging stations everywhere, landlords and employers should be forced to provide outlets.
Lmao. Unfortunately I live in the USA.
Freaking BASED.
But for long-distance trips, that doesn’t really hold up until we get battery capacities vastly superior to those of today. For countries with workers that have vacations, we like to go places other than home or work, sometimes. 😅
Anything with a Tesla logo on it is fair game.
He was already selling flame-throwers. That would be hilarious.
