“Far better driving dynamics than gas cars”? No way. Go throw a BMW 3-series around some corners and compare to the Model 3 - you will feel the weight of the batteries. I would have said compare to a Porsche but that’s a different price range. Note: I’m a big fan of EVs. I’m just saying that handling is one of their weaknesses until battery density gets a lot better.

The average people don't buy BMW or Tesla, they buy Honda CR-V. And they'll appreciate 500mi range far more than being able to take turns fast

You can’t get an EV at the same price as a ICE Honda CR-V, so that’s not an apples to apples comparison.

I watched a youtube video on this recently, and I believe that they never mentioned battery lifetime in it. This article said that one of the chemistries only lasts a few hundred cycles, but, because of the use pattern of the dual chemistry is "expected to last the lifetime of the vehicle". I really hope this turns out well, but given the current lack of specificity, I'm going to guess that overall pack longevity is…

Zero people drive 500 miles in a straight line on a daily basis though, so cornering ability is more important than 500 miles of range, especially when most gasoline cars (several diesels do) don't get that much range in a single tank. The biggest change for EVs is the ability to charge the car at home, though, so you wake up every morning with a full tank of "gas". An EV with only 50 miles of range would do great fo…

If people have to choose between being able to drive 500 miles with good enough handling and 200 miles with razor sharp sportscar handling the vast majority will pick the 500 mile car. Handling has long been good enough, most people don't get anywhere near what even their basic econobox can do.

I dunno. Honda doesn’t offer an electric CR-V, but they’re coming out with the Prologue, which is slightly cheaper than the comparable Passport.

Passport: $43k Prologue: $48k - $7.5k tax credit.

Almost no public road driven at the speed limit would even come close to testing the cornering ability of a car mass produced in the last few decades.

It is a bit different from the rocket equation. The impact of weight on energy consumed per mile in a car is not particularly large. You can add hundreds of pounds and the impact will be negligible.

At least if you have regenerative brakes. Otherwise weight matters in stop and go traffic quite a bit.

Are there any EVs without regenerative brakes? As soon as that technology matured, given how much geopolitics is about energy, it's surprising to me we didn't mandate it's usage.

BMW, build a charging network. That’s really the most consequential thing for drivers.

But don't forget to make it app only, because we don't want to build charging network which would be actually useful.

The UI should be: you plug in and it gives you power and your credit card pays automatically. Done.

You never need to touch or see your credit card or phone at any time before, during, or after the charging process.

Guess what kind of EVs work this way already.

Five years late.

I completely agree that chargers need to have simple payment methods, but doesn't the largest public network (Electrify America) already work this way? Yes they have an app, and you can get cheaper prices if you pay their subscription, but you don't need to use it. You can just pay with no account using the card swiper on every charge point, I'm pretty sure.

I’d rather not swipe a card or use an app.

Mercedes achieved a 1000km range with a regular 100kWh battery by making an extremely efficient car with a drag coefficient of only 0.17 [1] [1] https://en.wikipedia.org/wiki/Mercedes-Benz_Vision_EQXX

The unfortunate thing with the whole drag-coefficient game is it ultimately results in fish-shaped cars and zero unique designs.

Between EVs and crossovers we're suffocating in this current era of uninspired automotive design where it seems like mfgrs take a single car model, open it in Photoshop, resize by 50/70/110/130%, slap on new badge and call it a day. Audi & Subaru are some of the worst modern offenders here.
