"You think it would be hard to schedule a 30-45 minute meal somewhere once every two weeks?" I think there is an issue that may not be obvious with the charging time. Let's say for the sake of argument, sure, people can tolerate taking ten times the amount of time to charge as filling a gas tank. But what that means on a large scale, if everyone switches to electric, is that we need ten times the number of charging s…
Everyone charging at home in off-peak hours "fills in the bathtub" on energy usage charts. Peak demand during the day is huge, and it drops off substantially at night. We already have the power capacity to support every car switching magically tomorrow to EV so long as everyone agrees to charge in off-peak hours. Yeah, there's absolutely no reason for chargers to be rare. In much of the world we have the electricity…

I have an opinion (backed by a consensus of scientific practitioners) on the burning of fossil fuels (because of rampant climate change) in products because someone feels they need it versus a legitimate need. There's no point in arguing about an entitlement complex of a subset of the population ("right to own a pickup truck"), just gotta drive progress forward so people make better choices (behavioral economics) or…
If we are wanting to save the earth, then maybe instead of buying an $80k Tesla, people should buy a much cheaper Nissan Leaf (or ride a bike) and put all the money saved into carbon offsets.
Over the long haul an electric car should be superior in total lifecycle emissions relative to a comparable ICE or hybrid, but Tesla’s questionable initial build quality (reworks figure into total emissions!) and odd design choices (like needing to replace the flash unit for the MCU, semiconductor manufacturing is highly polluting), I would question the “greenness” of Tesla in comparison to other makes.
That said, overall it feels unproductive to focus only on a car when thinking about the total impact of oneself on the environment. Someone who drives a brand new Tesla, lives in a single family home, and eats steaks every night I would guess has a larger impact than someone who drives a used Corolla, lives in an apartment, and eats lentils every night. Personal transportation matters, but it’s a part of a larger whole that’s about consuming much less.

I looked at the lighter weight BMW model 3 series. They were either smaller engines (not fair since the model 3 AWD is already faster), or RWD (again not fair to compare to an AWD electric). Seems like 8% is about right to me.
If you look at the Model S which starts at 4800 pounds and Model X which starts at 5000 pounds the math works out very differently.

I've never had an apartment offer power at the parking lot. I couldn't buy a non-hybrid EV until a solid majority of them install that (either metered or on an indoor switch if I have an assigned space). Street parking is a harder problem.
You have never had an apartment offer power at the parking lot? Isn't that an issue with your landlords like any other apartment feature/benefit? Isn't that the same as price shopping for an apartment with in-unit Laundry or up-to-date Appliances? Maybe the Landlord doesn't presently see a need for such a convenience, but they should be willing to compete, open to suggestions and the right sort of incentivization, right? (At least, so claim the free market folks.)
Do you even need to charge at home? What's your daily commute, can you buy an EV with enough range that a supercharge once every two weeks will do it? That's the exact scenario discussed just posts above, this discussion is a flat circle.
Can you charge at work? Can you charge at the grocery when you are running errands?
Most Americans can, statistically, find a range in an EV today that they could charge once every two weeks and handle 100% of their average work life. Yes, everyone has an anecdote of how they are a special outlier that needs personal attention to their complaints.
You couldn't buy a non-hybrid EV, or you just aren't willing to put the work out into figuring out any sort of strategy or plan? It's not even rocket science. Electricity is everywhere and this should be really easy for everyone to figure out.
Does the building you are parked outside of have electricity? If yes, ask if it can give you an outside plug. That's it. Level 1 charging is that simple.
Level 2 charging is nearly as simple: Does that building have Dryers or any other reason to already have 220+ Volt A/C circuits? (Maybe you are somewhere like England where that's actually the wall sockets.) Get a "dryer plug" installed in the parking lot. Admittedly we use a bit fancier of a plug socket in that case, but the basic electronics are the same.
You aren't probably going to get a Level 3+ supercharger at an apartment complex any time soon (though it depends on your municipality and electric company and their goals for subsidizing the fun), but you probably don't need it. In most cases it's a lovely either/or: Level 1 or 2 charging at home/work, slow and steady every day, or Level 3+ charging in short bursts every two weeks or so. (Though it's not an exclusive-or; you could do both.)
There are options already. None of these are hard problems to solve. We have the technology, it's just amazing we don't seem to have the will or the imagination, at least in terms of how often these same questions come up in repeat on HN comments, and HN is an audience I'd expect to be more willing to explore creative technical solutions to problems rather than to just stop at the first anecdotal problem to mind.

I own an F150 I inherited from my grandfather. As much as I lust after Teslas I wouldn't trade it for an electric for one simple reason: my F150 is what I drive if I must drive at all when it floods. AFAIK you cannot and should not submerge the motors or the battery on an electric car. Still, that's an edge case.
Telsa model 3s act as boats during floods. Have a look at youtube, there are numerous videos of people stranded in their engine flooded car and a Tesla floats right by.
I don't think the Ford dealership would warrant me driving an F-150 through several feet of water either but fixing the issues that come from it are a known quantity. Not so much with an electric pickup.

If you look at the Model S which starts at 4800 pounds and Model X which starts at 5000 pounds the math works out very differently.
Sure, but they are much larger cars, 3 rows of seats available, etc. What cars are you comparing them to?
For the Model X I was really surprised how small the differences were. Compared to a G Wagon, which I'd say is really its competition, the difference in weight is about 8%. Compared to an X5, it's about 5%. If you consider the X7 to be the competition (which most people probably do), the X7 ends up being about 1% heavier.
And just to add it since I'm already doing this, I think the clear competitor for the Model 3 Performance is the M2 Competition. They're specifically meant to be track vehicles that you can comfortably use for your daily driver. This puts the weight disparity at 18% for that model. And just for fun: https://youtu.be/HycUgd6fTWI & https://www.youtube.com/watch?v=9Pu9046wX9g
So I guess the conclusion is electric vehicles are heavier, but as you move towards already heavy vehicles like SUVs the weight differences start to vanish. But as you move towards more smaller vehicles, the difference is much more noticeable.

> Now, unfortunately this should really have started in the 70s, Today's solar and wind boom was started in the 70s. It's kind of amazing how many people prefer the "bird in the bush" over the "bird in the hand".
That depends on definition. Yes, people were playing around with those things. But the idea that from the 70s to 2000s you could have systematically used wind and solar to replace fossil fuels is nonsense. Even today no industrial country is even close to having even all its energy from solar and wind. And were not even talking about transportation. For an alternative level you can look at France. France basically re…
There are reports that Scotland has been generating 200% of household energy needs from wind alone in 2019. That sounds close to me. Here is a news report, and wiki: https://www.cnbc.com/2019/07/15/scotland-has-produced-enough...

That's like the hall of fame entry for things that aren't actually true about electric vehicles. Efficiency doesn't get worse at highway speeds as compared to gas engines. EVs and gas engines spend more of their energy going faster against air resistance. evs are vastly more efficient than gas cars in terms of energey efficiency, thats why electric cars have theoretical gas mileage of around 100 mpg. But gas is a ver…
> thats why electric cars have theoretical gas mileage of around 100 mpg what good is that when your theoretical car can only hold 2.5 (maybe) gallons of fuel

> I think you're implicitly talking about a classic style 2-door pickup truck, but most consumer trucks these days seem to have four doors. Replace the shortened bed in the back with a cover and a third row of seating, though, and you have an SUV that's still going to be even heavier and more expensive. > Small two door pickup trucks are even more extinct, at least in the US. Very true, and as a small pickup lover th…
Well, I would say there isn't a huge penalty for the benefits, and it's nice to have 110% of your maximum expected needs covered rather than 80%. And big vehicles keep getting better and better fuel economy, plus scaled down versions aren't significantly cheaper. I think a major issue is that most of the cost of a car is not in the quantity of metal used to make the body/frame. So you aren't going to cut manufacturin…
That depends very much on the person. For someone with no kids and that needs to move very large cargo every once in a while, it may be the pickup truck that's the 110% and the SUV that's the 80%.
