What are you basing your they are not as clean assertion on? It's more likely that data center generation can be run continuously instead of turning on and off according to market prices. Can see the swing in amount of natural gas production during a day, https://www.gridstatus.io/live/ercot

New comment by brandonagr2 in "Amazon backs power plant that may become top source of US climate pollution"

It seems strange for this article to word this as a new or unusual source of pollution, natural gas is the primary source of energy in the US, adding 10% to existing thermal fleet in ERCOT https://www.ercot.com/gridmktinfo/dashboards is not a huge deal and its disingenuous to say this one plant will become a "top source of US pollution".

Solar generation buildout in ERCOT is also proceeding very quickly, the new Tesla megapack factory outside Houston and proposed new solar factory will help speed up the transition to sustainable energy.

Which part of "attack enemies" implies they were targeting innocent people?

You can, https://www.tesla.com/fsd

Are you trying to invent your own definition for self driving and quibble that supervision negates what the car is doing?

You are behind, FSD is already here, my car drove me to work today (fully self driving)

Starlink v3 satelites launch next month, the first starmind sats based nvidia chips sometime next year, large new factories for the needed solar panels are already half built outside of bastrop texas

There is a big difference between "something like" and actually passing the tests, I would be surprised if any non vision based system has the reaction time needed to pass the new pedestrian tests.

Obviously your priors are wrong, it can ace a blind spot warning test because it can detect a motorcycle next to it.

You don't have long to wait to see an obvious reason, the first v3 starship is in preflight testing right now.

Robotaxis in Austin are in the process of removing in car safety monitors, there is a chance you would get one today

Not mass production yet, but the first one rolled off the completed assembly line at giga texas last week

Sensor fusion is not far simpler, when the sensors disagree, and they will often, you have to pick which to trust.

It is amazing to see how many people here are confident they know the one true way to build autonomous systems based on nothing but wanting to confirm their biases

The benefit is capturing a larger percentage of the output of the sun than what hits the earth.

The surface area of the earth is the limit (which only gets sunlight half the time) and only gets 1 billionth the energy emitted by the sun vs relatively unlimited surface area of solar panels in space

Government run grocery stores are middle of the road? What would progressive ideas look like on that spectrum?

Nowhere to be seen if your head is in the sand. There are robotaxi pilot programs running in two cities, FSD 14 is actively rolling out to customers, and my car drove me to work this morning on v13. I don't see any lies

brandonagr2 — Thu, 18 Sep 2025 17:38:28 +0000

If a car has a physical child lock switch engaged, it's not possible to open the door from the inside even in an emergency.

Clearly rear emergency egress is not a requirement, a child opening the door while going down the highway is a much larger risk.

No, the horn is in the middle, the capacitive horn only steering wheel existed on early builds of the model S refresh (when plaid was first released), but after ~6 months they added the normal horn back.

Tesla does not use stereo/binocular vision, that's not how humans perceive relative motion at that distance either, we would depend on perspective and parallax

Have you met any humans? Or seen people driving?

Lidar is not a backup to vision, in a waymo both lidar and vision must be working, so you actually have less reliability as now you have two single points of failure.
