I heard really good things about the EV mustang from Ford. I wouldn't take this to be representative of EVs in general, but rather a remark on GM.
Is it GM or LG for making bunk batteries? TFA clearly states that GM believes they will be recouping this money from LG.

I think there's the 5 second cool factor but after that novelty you're probably just as disgruntled as the fact that you lost 35% of the range for your car. I hope the Chevy bolt is a rare case and stories like this don't pop up with the other upcoming electric vehicles. The new lightning F150 looks very attractive.
I don't see how electric cars are any different than mobile phones. So basically this means a 3 year life span in terms of battery performance. Regular combustion cars though also suffer reduced mpg so I am not saying this is an apples to apples comparison.

In Germany they are very serious about vehicle inspections, and insurance requirements.
Didn't the big German auto manufacturers literally develop the hacks to bypass diesel emissions inspections? I'm not sure I'd hold anyone up in a pedestal on this score...

If nobody buys a new car, how do you expect there to be any used ones?
Idk I drive my grandfathers old car and I think most people have at least 2 grandfathers

The problem here is the form factor of the cell as much as the chemistry. Pouch style cells are very difficult to regulate temperature in. This is a key reason why other automakers like Tesla use the small cylinder cells. Chinese companies like BYD have always used lithium iron phosphate. It has less energy density than lithium nickel batteries like NCA and NMC, but is cheaper. The patent was never taken out in China…
If batteries are easily swappable with minimal tools, then a lot of range concerns go away as well. I think battery ownership and care needs to be decoupled from the vehicle. I also think the federal government should enforce interoperable batteries between vehicle brands.
I for one would love to be able to take my battery out, swap it, have a few so some are always on solar charge. Be able to take one onto the boat. Use a new one for higher performance special occasion driving, and an old one for bumper to bumper slow commute which I can wrong every last mile out of. Have a few which default to home backup and can support the grid.
The highly optimised around the battery argument is very good. But it doesn't mean that we can't also have a company focusing on interchangeable batteries with a third party market.
Let the buyer decide. Neither solution will get 100% of the market, or zero. Why write one off right now with confidence when both could have a healthy market for the hugely diverse users (ie not just SV nerds)
The fed enforcing interop wouldn't be black and white. Just like Mercedes are allowed to sell super low MPG AMG Sports cars because they also sell lots of small city cars. The fed could encourage things in this direction without being black and white and mandating 100% of batteries be replaceable.
I think the downvotes of the parent comment here aren't what downvotes should be for. He or she brings up a very interesting point

The cars shape and structural components are designed around the battery. The cars software, motors, charging electronics, software, cooling systems, etc are all designed for the specific battery. The battery eats up a significant fraction of the cost of the car, and the systems designed around it a significant fraction of the remainder. Asking for interoperable batteries between vehicle brands is like asking for int…
It's not ridiculous but it does lead to this conclusion: That there is probably a single optimal "skateboard" type design. Manufacturers are converging on this anyway. https://en.wikipedia.org/wiki/Skateboard_(automotive_platfor... Then the real truth that no one wants to hear, is that there is no need for so many different types of passenger vehicles.

While nobody will come out and say it, I’m convinced based on some extensive early career battery system engineering and various evidence from tesla that what they do is put in much more raw capacity than they sell you and then limit with software the capacity of the battery. Early in the life of the battery this leads to slowed degredation and as the battery agrees the software uses more and more of the raw capacity…

I mean the Chevy Volt uses only 50% of it's battery capacity but it can more easily do that thanks to having a built-in gasoline engine that operates more like a generator for the electric engine. When I found out that they limited the battery for maximum longevity I was less stressed out about the battery life. They still degrade over time and until they become more modular like the Ultium system GM is putting into…

I’m not sure, it’s 24 hours of constant monitoring and fire suppression from a trained fire crew. Not something that’s scalable.
Where did you hear 24 hours. Sounds anecdotal. All fire crews are trained. Are you saying there are untrained firefighters? Do you think that you in your tech job are more aware of fires than a firefighter.
