I disagree with this line of thought. Spacex took a big risk to get to where they are, just because they happen to have pulled it off and it provides some “public benefit” doesn’t mean it should just be taken from them. And if it’s buy out that still doesn’t solve the problem because people value things completely differently.
This stifles innovation and the willingness to take on risk for a reward down the road. If you actually pull it off and reach some level of “public benefit” it could just be taken from you.

I disagree with this approach. Forced compliance by the “stick” approach I think never wins against a compelling “carrot” approach. Some people are reflexively defiant to what they see as arbitrary punishments for personal choices. Incentivizing smaller and more efficient cars is better. This is an electric truck, it’s still big, but would the net positives of someone buying an electric truck be better than a gas one regardless of size?
Not really. It’s not just the massively inefficient ICE drive train that makes large trucks dangerous and a poor fit for sharing roads with smaller cars or bikes.
It’s also the ponderous size the lack of visibility and sheer weight.
Cybertruck has all the rest of the problems. It’s in fact bigger and heavier than most trucks.
I disagree, I think this was a well researched and thorough accounting of a concerning trend.
Sometimes the opinions and facts provided challenge our worldview, but provide additional information and viewpoints to give us a more complete picture.
Same - this is the kind of article that would have been easy to write in a lazy finger pointing way, but it's clear they took pains to justify their arguments and IMO didn't fall into the anti-work reactionary trap.
Yeah I feel like this is the next stepping stone on a path we have been on for years. I remember Rich Rebuilds got rear ended in his Rivian and the total repair bill was somewhere around $30K if I remember right. I really do wish repairability was considered more not less, but with safety standards, manufacturing costs, etc it seems like cars are racing towards the cliff of just “discarding” if they have a problem just like the rest of consumer goods
With EVs this problem is getting a lot worse. In latest-gen EVs the battery pack is a stressed member of the frame. Any type of collision that distorts the frame will also imply a deformation of the battery module, which means instant write-off.
So if you think about it - if you first decide you need to go down the "structural battery" route to save cost and weight, you've already lost repairability if the frame is bent. Then moving to a cast frame doesn't really change anything.
Don't you lose repairability anyway if the frame is significantly bent?
AFAICT the actual batteries inside the "structural battery" are separate much smaller cells [1] that can at least be recovered from the bent frame and reused if undamaged.
Consider four factors: normal car performance, car's safety in a crash, car's repairability after a crash, and car's price. They all work against each other; no wonder that repairability is sacrificed to optimize the other three. (In a military vehicle the price is usually sacrificed instead.)
A salvage operation where you harvest raw cells is no where near repairability. That is one step removed from taking a crushed car selling it for scrap metal.
Indeed, not reparability but reusability. The cells are standard and can be readily reused in a variety of ways, unlike a badly bent frame / chassis that can only go to scrap metal.
The castings and frame are incredibly strong.
Or in other words; when those are damaged, the rest of the car is likely beyond economical repair. Even without insurance.
Tear it appart for parts.
The Ford Mach-E does the same thing. There's thin box frame rails as part of the traditional ladder frame, and the battery pack actually forms the floorpan and stressed crossmembers. Without the battery pack the frame will deform because there's no lateral reinforcement, making it this weird hybrid of a ladder frame and unibody that it shares with the Model X and Ioniq 5. Most EVs like the Bolt and the Ioniq 6 are unibodies however since they're just designed like regular cars with battery packs shoved where the fuel tank would normally go under the rear seat or rear hatch floor, and the battery pack simply reinforces the floor.
Its not actually the same. People constantly mix things up because the words people use are so wrong.
Structural packs are nothing new, lots of EV always had structural packs.
What Tesla is doing in the newer Model Y (called 'Structural Pack') is actually structural cells. That's the innovation. Where the cells themselves are glued together and sandwiched in a pack. So the cells themselves act as vertical enforcers. The whole back is basically filled with structural foam.
The only other company that is doing something like that is BYD but that is quite different as those are really big Prismatic cells stacked up.
Wonder if that's the same Rivian that was in a YouTube video that popped up a couple of days ago where some specialty repair shop was able to use nontraditional repair methods to fix the damage at a fraction of the quoted $41,000 repair cost.
Yeah iirc it happened twice to him, the first was a rivian authorized repair at the high price tag and the second was an alternate repair method they tried out at a much smaller price tag
With Cars I do believe there's a tradeoff between repair ability and crash safety to some degree. The Chassis has to deform to take the crash energy away from the passenger and the more it deforms the more energy gets absorbed.
This stifles innovation and the willingness to take on risk for a reward down the road. If you actually pull it off and reach some level of “public benefit” it could just be taken from you.
