Agreed that producing is tough, but what was said above about it being "vaporware" is complete nonsense though.

Really? Can you show me any video anywhere of someone actually driving a Rivian?

They haven't built one yet.

Is it any worse than what other manufacturers deal with? The 2019 Honda Accord shares some parts with the 2018 Honda Accord which shares some parts with the 2017 model... when something breaks in my Honda the first question is "do they still make/use this part or did they change it in newer models?"

Gee, I hope they have some kind of system to track that. Maybe software even?

You jest, but years ago I worked for one of the largest auto parts places. You have no idea how many times you'd input year, make, model, and trim, just to be presented with multiple choice questions. Nobody knew how big their drums were, in inches, or the number of blades on their fan, the length of their belts, etc. Apparently a lot of mixing and matching happens. Some folks legitimately had to give us a prior year for us to find the right part.

This sort of complexity is why I like pre smog era cars

I mean sure. But my gas vehicle is purely recreational, it gets a few hundred miles a year at most. I really enjoy teaching myself car maintenance and repair with it. Being an 80s car, it’s super roomy in the engine area and easy to work on.

No one is dying because I own and drive this car today. Someone might’ve died mining the lithium for my Tesla however.

This is all to say that your comment is reductive.

So it sounds like the range increase is for new cars? (Other comments made it sound like a software update to existing cars) I still wish there was more focus on range over acceleration, obviously electric motors don't suffer from general efficiency impact as ICEs do (an ICE with superior acceleration seems to take an efficiency hit at all speeds), but how much of that "faster acceleration" impacts efficiency over th…

basically none. I've read that many electric motors are most efficient at 80%+ load...

The problem is more that you hurt efficiency when accelerating fast. I'd rather a moderately reliable increase in range than improved periodic acceleration.

Essentially this is: How much does (say) 25-55mph in 2s vs. 4s cost for overall distance in normal traffic.

That said I have better things to spend 60k on than a car. (my last car was $18k, and 42k can be used for a lot of good things that aren't a fancy car. That said I would rather a car that can accelerate faster than a Prius C - my old 9k Yaris did much better, even though it used more gas)

You can like something without wanting to go back to it. It's nice being able to fix your own car, but great fuel efficiency and low emissions is also nice.

Comment came a year too late.

Fortunately for you, in 2021 you can make the exact same mistake just one order of magnitude further along.

Yep. Just went thru that 2 days ago with my father's GMC W series truck. The air filter I got from the retailer is for the previous generation, even though that's what their system says for the truck.

I had to hand the old filter to the store staff and have him copy the FRAM part number.

Range and acceleration mostly go hand in hand. Much of the constraint on acceleration is how much power you can pull from the battery pack, and that gets better with larger batteries. It’s not like a normal car where high acceleration means a big, inefficient engine.

Agreed, that was why I noted the efficiency model for an electric engine is superior to ICE. I'd just rather "normal"-ish acceleration in traffic with range improvements over high max acceleration. I'm sure you could also reduce engine weight if you don't have to rely on extreme acceleration.

They're re-introducing the lower cost model, interesting move right before quarterly earnings get announced. I have to assume this means sales have been poor. > In addition to our Long Range and Performance variants, we’re also re-introducing a lower entry price for Model S and Model X by bringing back our Standard Range option

In the autonomy presentation yesterday they said they could create more robotaxis if they ship smaller batteries. So I wouldn’t assume it means sales are poor. They’re focused now on building out a self driving fleet of customer cars, which they plan to activate as taxis in the future.

For metric folks, this equates to nearly 600km. That's about as much as I want to drive in the space of a single day. Conceivably however, automated driving could mean doing longer distances. And at a cost much less than an airfare - just a lot more in time.

I can't wait to sit in my car one morning in Los Angeles, punch in Seattle, then wake up the next morning arrived.

If self driving trucks are on the horizon, why not self driving efficiency apartments? :)
