The solution is to eliminate self-driving cars and instead invest more in mass transit and walkable neighborhoods.

You’re better off spending it on stuff like mass transit and the like. It won’t just all disappear at some point in the future.

You won’t be saying that once the market crashes. You’ll realize that there are much better ways of spending that money. Like far more practical emissions reducing solutions.

Not really. It’s mainly about gaining market dominance on a technology they think is the future. They’ll build them right next to the massive coal plant alongside a million other things they’re subsidizing.

It’s the result of massive subsidies. When they stop, this market will crash like a house of cards.

Mass layoffs is going to make it worse, not better.

There will come a day when people will realize that even tech companies aren’t worth that much.

I suspect there is something more to this than just that. After all, the car in question did this:

Earlier this month, a Cruise robotaxi notably ran over a pedestrian who had been hit by another vehicle driven by a human. The pedestrian became pinned under a tire of the Cruise vehicle after it came to a stop — and then was pulled for about 20 feet (six meters) as the car attempted to move off the road.

It seems like there are unsolvable safety problems going on.

Everyone with a brain has left Xitter.

I’ve come to realize that many a tech company are ran by morons.

Tech has become a scam in many areas. It’s just doing the same thing as it always has been, just with an abusive corporate master. The goal is to scam the investor into funding bad ideas, or use that funding to undercut the competition. It is rarely about innovation anymore.

Are you talking about FCEVs? You can also include directly electrified vehicles, but that is mostly mass transit.

And yes, electrification as a whole will succeed. But BEVs probably are not. I call them fads because they are just toys for the rich and they are unlikely to be affordable for most people.

It’s wrong because li-ion batteries at the time were way better than what it claims:

This is from 2009, and already we reached 675 Wh/L. So there’s no way the DoE link is true.

Except those fundamental limits are far higher. The fact is that hydrogen stores energy at 120 MJ/kg. Even at 5% weight efficiency, that’s 6 MJ/kg. Or 1,666 Wh/kg. At 10%, it is 3,333 Wh/kg. Far beyond any battery.

Your link is seriously lying. 8x is the gap between lead-acid and li-ion batteries. The claims are simply impossible. The author must be unknowingly comparing lead-acid battery powered cars to li-ion battery powered cars. I cannot see any other way his claim is true.

A lithium-air battery is literally a fuel cell. In fact, what did you think hydrogen fuel cells were this entire time?

I would say that’s pretty unlikely there will be a 10x improvement in battery chemistry. At some point, we will have to deal with the fundamental limitations of the technology. That will likely imply a different kind of EV. Other conversations in this thread have brought up the FCEV, which is honestly the mostly likely guess for what comes after the BEV. In other words, the solution is to move beyond batteries, not pretend we can just improve batteries ad absurdum.

Also, this is basically the point of the book The Innovator’s Dilemma. Technology does not improve linearly exclusively. At some point, major shifts in the market will have to happen. If you think about this problem honestly, you probably have to conclude that the limitations of the BEV must be solved by a big leap forward, not incremental improvements in batteries. And if you can reach that conclusion, then you must realize that the BEV has to be a transitional technology. Perhaps, even a fad.

For one thing, this is sad because even more of the Internet is no longer reachable. The Internet shrinks, and will continue to get smaller as enshittification continues.

But on the other hand, this is really starting to look like the death knell of Twitter. It’s quickly becoming extremely inconvenient to see any tweets on Twitter now.

Again, we can all see your votes!

So basically downvote = disagree again.

Again, acting like you’re on Reddit just makes you a loser.

Are you going to reduce this post too? Is this post just another example of bad faith posting? Are you really that shallow?

LOL, proven to not just be a loser, but a dishonest loser too.

PS: You do know all favorites/boosts/reduces are public right? Like I can see that you are reducing all my posts. I’d prefer it if you don’t carry over this bit of Redditism.

LOL you’re such a loser.
