In that case I'll hold off on buying an EV until these new, futuristic and not at all crude vehicles get made. Hopefully by then, we'll have solved the problem of how to sustainably fuel both the manufacturing process and the fuel

Interesting thing to think about, eh? I think we are going through a permanent shift in the availability of electronic components, and this idea will become more widespread (that is, the reliability of supply chains),

>This argument is only being made because widespread EV adoption is a new phenomenon and they are still a fraction of the market of ICE cars. No, it's being made because the manufacture of an EV and all of its component parts requir

Getting any kind of performance and efficiency out of an electric motor requires a sophisticated controller, which is why development of EVs stalled for so long. Semiconductor tech has only recently progressed to a point that makes this via

>Which is why they were both invented around similar times. The ease with which you can make oil-based fuels convert chemical energy into mecahnical motion, is the reason that EV development largely stopped until quite recently. Efficien

That's an interesting argument. >Making vehicles that people don't want isn't sustainable From a business standpoint, yes. However, making unsustainable (and unobtainable) vehicles that people do want, at least keeps the

My bad, missed those. My point still stands - a dependency on electronics, and especially cutting-edge electronics, makes you dependendent on a complex and fragile global ecosystem.

All of the things you mention are electronics, which are at least (arguably) optional, or at least minimal, on an ICE. I am not saying an ICE is a better idea. I'm saying that an EV is, by some definition, unreliable from the drawing b

At least that is an option for a non-EV! Maybe Hyundai should work on a mechanical or otherwise analogue motor controller.

I understand the argument. What makes their trust-funded operation better than all the others? Do we just have to take their word that they are the morally superior trust fund baby? After all, that phrase is typically used as a slur against

I'm very curious why this statement is so unpopular. It's demonstrably true, at the current moment.

They get away with it, because the selected news stories fit the predisposed beliefs and biases of their readers. Just like all media. A related point - The Guardian makes much of the fact that they are funded by a trust fund, arguing that

When people talk about the "reliability" of EVs, I think that a hugely-overlooked aspect is the reliability of the supply chain (including engineering, design, and component supply). It's all very well having a fantastic desi
