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

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.

A complete lie that drives me to work every morning? I'm not seeing what the lie is

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

> Most humans also don't get in accidents

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.

The hyperloop idea (which was just a presentation with no plans to build it) is an entirely different thing from the boring company tunnels

New comment by brandonagr2 in "CO2 Battery"

brandonagr2 — Fri, 25 Jul 2025 17:38:40 +0000

What is the negative externality of recycling batteries? That is way better than having to mine minerals out of the ground, eventually there won't need to be any significant mining and all the battery minerals will be in a constant cycle of being used then recycled

Just because it's supervised doesn't mean its not self driving

No, a self driving car can be either supervised or unsupervised.

I'm required to supervise my car while it drives me to work, but it is by definition fully self driving, controlling all aspects of the vehicle while I sit with hands off the wheel watching

This might surprise you, but you have no idea what you are talking about.

You don't have to believe anything Elon says, just look at what he has done for the past 22 years. SpaceX was founded on the singular purpose of getting to Mars. Elon originally tried to buy ICBMs from Russia to launch to Mars, when that fell through he started his own rocket company. The entire tech stack and rockets being built are to reduce the cost of mass to orbit by the orders of magnitude needed to colonize mars. There is no other reason to build something as huge as Starship. Elon IS funding getting to mars by himself, the Starship program is mostly self funded, with the Artemis HLS contract coming well after the program was started.

You are replying to an anecdotal blog post to say that a comment that is just an anecdote is not a useful contribution?

You think it's useful to have a blog post to reveal the shocking truth that mass manufactured products aren't 100% reliable? A lemon could be produced by any auto manufacturer and the customer could have the same experience

And yet Tesla has industry leading brand loyalty, what do you think is a better predictor, an opaque number computed by Consumer Reports from an unknown formula that combines feedback about non reliability items from users who bother to respond to consumer reports questions, or what 87% of consumers decide after experiencing a Tesla?
